Video Transcript for Fifth Wheel Base Rail Kit Installation - 2007 Chevrolet Silverado

Today on our 2007 Chevrolet 2007 Silverado Classic 2500HD we'll be installing the Reese Quick Install Custom Base Rails and Installation Kit for Fifth Wheel Trailer Hitches, Part Number RP500064-58. Now that we have the rear tires as well as the spare tire lowered out of the way, we're going to first begin here by removing the heat shield from underneath the passenger's side of the vehicle. You'll need to cut along these lines of the heat shield because these are areas to access just above it to put our rails for the fifth wheel hitch in. Now that we have our heat shield cut out of the way, we're ready to go up into the bed of the vehicle and take some measurements and line up our front rail. Now, because this vehicle is a long bed, or eight foot box bed, we'll be measuring fifty-two and three-eighth inches from the rear of the bed up to the rear edge of the base rail. Now that we have it measured properly and centered on the bed, I will go ahead and make four marks in the four outer holes of the base rail. Once we have the marks on the bed, we'll go ahead and use an eighth-inch drill bit to put a pilot hole in each location. On the driver's side you'll want to be very careful as you're just above the gas tank. Now that we have our pilot hole in each of the four locations, we'll go ahead and hold up our side-plates to make sure our holes line up with the side-plate holes. Now we'll go back up into the bed and step up the hole to a nine-sixteenths hole.

We'll need to stick our carriage bolts in from the top. Our carriage bolts are half-inch by two-inch carriage bolts and we'll need to use a U-shaped spacer block on the top of the bed on this front rail. We need to do this so we don't crush the bed and we have metal-to-metal contact all the way through. We'll do this for both the driver and the passenger side. Now we're ready to begin here on the driver's side. We'll put our side rail on and bolt it to our front base-plate.

We went ahead and used the U-bolt that comes with the kit to help hold it in place. The hardware we'll use for these two locations. For the half-inch U-bolt, we'll be using half-inch flat washer, a half-inch lock washer and a half-inch hex nut on each side of the U-bolt. For the large hole on the side-plate we'll be using a three-quarter inch by one and a half-inch hex bolt, a three-quarter inch flat washer on both sides. We'll put a three-quarter inch flat washer onto the bolt, feed it from the inside of the frame rail to the outside, through the side plate. Then we'll put another another three-quarter inch flat washer on, followed by a three-quarter inch lock washer and finally a three-quarter inch hex nut.

This will be the same hardware used for both sides. We'll take our fifth-wheel head, it doesn't need to be assembled at this time, we just need the two portions that go into the base rails. We need this so we get the proper spacing for the rear rail. Now that we have our measurements correct and the rail is positioned properly, we'll go ahead and mark the holes that we'll need to drill this time. For the rear rail, we'll be using the second hole in for all four locations. Now that we have all four of the rear holes marked we'll go ahead and slide the rail out of the way and repeat the process of starting out with a eighth-inch bit and then stepping up to a nine-sixteenth. Since we have already have our side-plates on we should be drilling right through our side-plates underneath. For the U-shaped spacer block on this rail we'll be putting them underneath the bed because we drill through one of the up part ridges of the bed.

We'll go ahead and put the carriage bolts in, followed by the spacer blocks with the offset hole, a half-inch lock nut, a half-inch lock washer and the half-inch lock nut. Now we'll go ahead and tighten down the side-plate hardware as well. We'll first start out by tightening down the half-inch U-bolts and then torquing them to manufacturer's specification. Followed by tightening and torquing the three-quarter inch bolts that we installed at the rear of the side plates. We'll do this for both the driver and the passenger side. For the front base rail you'll notice that there are two holes in the center of the rail. The center hole at the rear of the front cross-plate, again we'll be starting with the small eighth-inch bit stepping up to a half-inch bit this time. For the rear base rail we'll be drilling it in the same location but instead we'll be using the front hole on this rail. Once we have each of the holes drilled we'll put our half-inch carriage bolts in but this time our hardware underneath will be a little bit different. It will be a half-inch conical tooth washer followed by a half-inch hex nut. Once we have these tightened down, we'll again torque them to manufacturer's specification. Once we have these two locations tightened and torqued down we can go ahead and reinstall the spare tire as well as put the wheels back on. That will conclude our installation of the Reese Quick-Install Custom Base Rail and Installation Kit for Fifth Wheel Trailer Hitches, Part Number RP500064-58, on our 2007 Chevrolet Silverado classic 2500HD. .

2006 Dodge 2500HD

I was a little leery of installing a fifth wheel hitch to begin with, but after watching the videos from etrailer a few times and reading the instructions a couple of times, I decided I could do it. I installed the RP50064-58 kit for fifth wheel hitches and the Reese 30083 Fifth Wheel 20K w/Round Slider Unit on my 2006 GMC 2500HD short-bed. I had my three grandsons, ages 2, 3, and 7, helping me. The installation went really smooth (other than the younger children occasionally running off with tools) and I am very impressed by how sturdy it is. Now I am looking forward to receiving the Stromberg Carlson 100 Series 5th Wheel Tailgate with Open Design that I ordered. Thank you etrailer! You make it fun and easy!

Ha ha ha Michael I can relate to that have a 3 and a 7 years old and every time I work on something they are there to help the 3 year old more like wants to do it himself . Planing on installing a 5th myself and was thinking they could be of help steping on the bolts top side so I can put the nuts to the bolts, looks kinda hard. Good luck with your venture . Larry Esparza El Paso Tx

2006 GMC Sierra

I was a bit nervous at first installing the rails that would eventually hold the weight of a 16,000lb camper, however after reading the instructions and looking at the quality of the parts, I felt alot more comfortable. The installation was very easy, and with the large side plates, I feel alot better knowing the rails and hitch are secured to the frame with more than those small pieces of L steel that normally come with the kit. Install only took me about an hour and the hitch is very solid!

2006 Chevrolet Silverado

I have a 2006 2500HD with an existing gooseneck hitch that is welded in place between the frame. I had thought the "custom-fit 5th wheel" brackets would still fit so I ordered them so as to not have to drill in the truck frame. Unfortunately, the gooseneck channel is in the way of where the "U" bolt needed to go on the back side of the frame so I have to return this and get the "universal" install kit / rails. It will still be fine but I was trying to not drill in the frame any more than necessary.

I just wanted to pass this along incase anyone else had the same setup. It will save you some time, frustration, and shipping money :-). It was my fault (not etrailer's) .

I attached a picture showing where the bracket is with the gooseneck channel behind it (in the way). Hope it helps someone else.

2014 Chevrolet Silverado

Not as easy as the online videos would lead you to believe. However I did manage to get it installed. Getting the spacers nuts and lock washers on the bolts over the gas tank on my 2014 Silverado were a real SOB. Dropped 3 lock washer into the shroud over the gas tank while trying to accomplish this. Ended up taping the nut and lock washer to my wrench to get them in position while someone turned the bolt from inside the truck bed.


Poorly packaged at the warehouse which caused a box failure enroute to my house. I REALLY needed this for the weekend and will now have to either borrow a truck with a hitch or find a kit locally. Customer service blamed UPS. I disagree. Had the box been secured properly from etrailer to begin with, I wouldn’t be writing this review. I will not order anything heavy from them again.

2002 Chevrolet Silverado

Very fast shipping for the 5th wheel sliding hitch, rails and wiring ! Installation was very straight forward although the instructions were a bit vague. Watched the installation videos a couple of times which was a big help. Took about 4 hours for everything including wiring. Could have been quicker if I took off the rear wheels and lowered the exhaust but just worked around them. Picked up my new 5th wheel a week later and was very happy with the hitch - No problems at all. This was installed on a 2002 Chevrolet Silverado 2500HD.

Matthew W.


Still very happy after thousands of miles !

2005 Chevrolet Silverado

Instructions leave something to be desired.. and every bolt needed for every variation of truck this kit can go on is included, so lots of leftover hardware. Surprising for a 'custom' kit (not universal).

Other than that, got it installed on my 2005 Silverado 3500 in roughly the time advertised. Almost. Still trying to figure out how to tighten the last nut that is really hard to reach.



No issues after a year. Kudos to etrailer for asking since so many people jump the gun quickly with glowing reviews only to realize disappointment soon after. Not so with this kit all is still good.

2008 Chevrolet Silverado

It wasn't so easy for me as I am 80 yrs. old but I got her done in a days time and it works fine, all the measurements in the directions were right on.



The kit worked fine but the camper was too much weight for a 12 ton, sold the truck and bought a 34 ton with fifth wheel in it

2006 GMC Duramax

This kit was a perfect fit on my 2006 Duramax crew cab. Installation was a breezy and it did not require any drilling or welding of the frame. The instructions were good and all necessary bolts and nuts were supplied ( along with a lifetime supply of spares). I would highly suggest this seller and their kit if you need fifth wheel rails installed in your truck.

2014 Chevrolet Silverado 1500

Installed this custom kit on my 2014 Chevy,fit like a glove.A few things I didn't have to do was remove the exhaust pipe or cut the heat shield,I had enough room to put my hands and reach the hardware.But you should lower the gas tank.
I don't have access to a hoist,so I had to do my work in the driveway while fighting off the mosquitoes.

Leroy N.


What a great idea,no holes in the frame,Still working good ,no issues.

2002 Chevrolet Silverado

I brought this 5th Wheel rail kit to a local Hitch Installation and Welding shop, and they installed it for me in one day. I brought the Hensley Trailersaver TS3 5th Wheel Hitch as well, so that the whole assembly could be line-up precisely as prescribed, with the center of the Kingpin at 1-5/8" forward of the truck drive axle center line. Great product by Reese, that fit my 2002 Silverado 3500 perfectly. Would recommend Reese products to anyone contemplating towing an RV/Travel Trailer.

2014 Chevrolet Silverado

I bought a new Chevy 2014 Silverado Double Cab 4X4 with the 6' 6" bed and needed a bed rail kit to mount a fifth wheel hitch from another vehicle. Plan on spending 6 - 8 hours to install it if you have no previous experience with this installation. Make sure you have less than 1/4 of a tank of gas as the installation requires lowering the gas tank down about 12 inches. You will also need to remove the spare tire. You will save yourself a lot grief by doing these two things first. Also note the position of the bolts that hold the rails to the brackets, the front rail uses the outer most holes. The rear rail uses the second set of holes inward from the end of the rail. If you have a bed liner, trim it first before doing anything else.

This is a well designed heavy duty product. I have purchased several different products over the years and never had a complaint. Their service and pricing have been great.

2012 GMC Sierra

Per instructions, removal of the vehicle heat shield was a beastly process. Modification of inner fenders was never mentioned in the instructions, had to modify the brackets to eliminate interference fit with hanger on the drivers side on the frame. Had to customize an existing bracket to allow access to mounting bolt on driver side. Also had to modify the frame to gain access to hold 3/4" bolt head for tightening mounting plates. It would have been much better to have had 2 throw away short open end stamped wrenches supplied with the kit in exchange for many extra bolts and other hardware. Once custom fabrication was complete it does work fine.

Chevrolet Silverado

I bought these quick install base rail plates instead of the universal fits all-fits nothing well angle plates that I had used on a different truck. Watch the video e-trailer has on line in the help section and the video is much better than the instructions that come with the plates.

My install went just like the video except the truck was only 2 days old so I didn't want to drop the exhaust or the fuel tank. It was tight between the fuel tank and the bolts that hold the rails in the bed but do-able.

The exhaust side was easier and I didn't have the exhaust tin shield like on the video but it was still tight but easier than the fuel tank side.

Using the measurements like in the video ALL the holes lined up like through the bed like they were supposed to with out any reaming of the plates or brackets.

The plates on the frame with the spacers worked great just like in the video and are worth the up charge of $$$ instead of using the universal angle supports.

With my Silverado being only 2 days old I was not going to drill any holes in to the frame for any reason to have chevy void my warranty so these bolt on plates using exsisting holes were the nuts!!!

I bought new bed rails for my fifth wheel as it would just have been to much of a pain to mess with the rusted bolts in the old truck.

All the hardware was there, every thing was packed waaaay too good, and it all came fast.

Who could ask for more

2005 Chevrolet Silverado

Like a few of the other reviewers, I decided that the custom brackets for my 2005 Silverado 2500HD with 6 1/2 foot box was the way to go because I didn't want to be drilling and fitting the smaller brackets under there. Here's some thoughts. Yes, the spare tire really needs to come down - that took me about 2 hours, as I have never had it down before and had to keep referring to the instruction manual. Making measurements for the rail placement and drilling the holes in the bed was the easy part, as was using tip snips to remove a section of the heat shield underneath. The hard part was drilling the optional hole in the frame for the 1/2 inch bolt and fishing the bolt through on the drivers side (passenger side was an easy fish). I started with 1/2 inch hole for the 1/2 inch bolt - ended up drilling a 9/16 hole so the bolt would come through. Still, I do feel comfortable that this bolt provides extra security/rigidity to the brackets. The other hard thing to do was get the rectangular offset hole plate and lock washer attached to the rail bolts up by the fuel tank. Ended up hot gluing the lock washer to the plate because I was out of fingers to hold the pieces up there and thread the nut onto the bolt - ideally one would need to be part stretch armstrong and part contortionist. My total installation time was closer to 5-6 hours - but when it comes to something like this, I would rather be slow and thorough than fast and miss something. The kit contained everything needed and even a few leftover parts - so don't be concerned. Towed my new trailer home 2 nights ago and was pleased with the set-up and how it towed.


This is my first time pulling a 5th wheel but not the first time traveling in a RV. Looking at the installation kits for these 5th wheels was a learning experience! Not many places sell the Quick-Install Custom Base Rails and Installation Kit. Since this is my first time pulling I wanted the security of knowing all four bolts holding the Base rails to the frame were attached to bracket. I'm not the one doing the install, but from what I see, the time should be cut by 1/3 from the other way of installing the base rails. eTrailer was the only one of the 5 websites I checked that had what I was looking for.
Robert G from MI


Parts arrived in a very short time and all fasteners and directions were in the boxes as expected! Installing was not quick and easy as I thought it would be. Fat fingers I could have done without. My son helped with most of the installation because 4 hands are required! The quality of the product is great as I expected too!

Joseph S.


The product is working as I expected. The sun and weather has taken its toll on the paint, but that to I would expect. Great kit overall.


I was happy with this set of rails. I chose to have them installed, but my installer said they fit well and were an easy install. I have used them now with multiple 5th wheel and gooseneck hitches.

Ram 3500

Very good products that are built to last. Nice thick powder coat. My order was an odd one . I ordered a fifth wheel base kit for a Chevrolet 1500. I don’t think many 1500s put fithwheel kits on them, but it’s for a 1500 towable Camper , very short and light. The system kept trying to send me the kit for a newer 2500 or 3500 I guess but we finally got it right with the required pieces to get it mounted. Nice and respectful service on the phone.

2008 Chevrolet Silverado

This product was well designed and came all the materials that were required and additional for the various other vehicle installations. The installation was as stated, the only drilling was thru the bed floor. The hardest part of the install was being able to start the driver side rail bolts to the frame bracket. To many items in the way (fuel tank, brake controller, dual exhaust), but overall an excellent package. Took about 3 1/2 hours with two guys, a third would been helpful at times. 2008 Chevrolet Silverado LTZ 2500HD Diesel Crew Cab Short Box

2004 Chevrolet Silverado

etrailer's web site is full of info and videos and ordering was a easy. Product came in one box and looks like it may have broken open in transit do to weight (85 lbs.) However box was taped up and nothing was damaged and all parts are there. It appears that the fasteners for multiple applications are supplied, so there may be some left over. I will be installing this into a 2004 Silverado 2500HD that had previously had a 5th wheel hitch so I'm hoping that the preexisting holes line up.
Will be towing a 5th wheel camper.

2015 Chevrolet Silverado 1500

etrailer had the best price of all of the online suppliers of this product I could find. Quick shipping too. My only issue, and it's really not etrailer's fault, the included instructions left a lot to be desired. But to be fair, I found a YouTube video of this assembly being installed and while it looked pretty simple and straight forward, the video even left out some key issues...such as a brake line that was right in the way and had to be "relocated". Other than the instruction issue, I would give etrailer 5 stars.


Ordered the Reese Quick-install rail and installation kit for my 08 GMC because the 05 brackets I had did not fit the 08. A friend and I installed it in about 2 hours, had difficulty installing one bolt above the fuel tank but this was to be expected. The instructions were clear and easy to follow. The parts fit perfectly and looked like a professional installation when finished.

2008 Chevrolet Silverado

Order was received quick as always from etrailer. Installation was straight forward; had never installed one before and was able to get it done in one night. Yet to tow the camper as we are waiting to pick it up. After installation I trimmed the bedliner so the rails were accessible for mounting. This was on a 2008 Silverado 2500HD

Chevrolet Silverado 1500

The instructions for a 1500 series is horrible, for the back rail to in stall it you have to have your hitch for measurements thats not the way you should install the second rail, give precise measurements.
2nd it took 2 people 8 hrs to install due to the wrong instructions on what holes to use on the frame brackets but, we inprovised fot the parts to work. I wouldn't recommend to all one. I would buy Curt next time.
