Upgraded my truck to a 2019 F250 Superduty. Received my new rail kit and mounting brackets. Fits perfect!

2017 Chevrolet Silverado 1500

Very happy how soon the product I ordered was at my door step. 3 days after I ordered it. Put the base to my 5th wheel on my 2017 250 diesel sd took me around 5 hrs, would have been faster with 2 people. The base fit my husky 16k prefect when I done torquing all the bolts. Going to use this hitch to pull my 29.5 Durango EZ 1500.

2017 Ford F-350 Super Duty

The kit arrived within a few days-very happy about that. very easy to install. the directions were clear and pictures good. I went to the trouble of using a sharpie to mark the part numbers on everything before I started just to keep to all straight.

I would note that on the 2017 F350 diesel the only problem bolt was on the driver side inline with the DEF tank. long skinny arms with flexible wrist is ideal (not what I have). I would also suggest taping the shims onto the outboard frame brackets to save yourself some frustrations. otherwise they are difficult to get and keep in place, especially on the driver side.

the two nuts that go inside the frame tube come on/with a nice handle although a bit light on the wield. here again save yourself and tape the shims on before you try to insert two things into that hole, align and fasten the bolt-by yourself. I used an extension with wobble head and socket to turn the bolt while holding the nut "assembly" in place.

I did remove the rear wheels and fender well liner-a must.

Lastly, great customer service on the phone. Pleasant and patient answering questions.

Still love the product. Thank you for checking back.

2017 Ford Edge

Very easy to install. Measure twice, drill once. I used every piece of galvanic corrosion tape to protect the aluminum bed in the kit, probably could have used a little more. Even though I painted the edge of the holes after drilling, maybe some sort of insulator could be used there also.


Easy installation, quality product!


I returned my purchase and was horrified how much I was soaked for returning the items, way too much.


The product has served we well. We have travelled 14 states and about 15,000 miles pulling out fifth wheel rv with this rail system and no failures. I would say the kit is idiot proof but I was proven wrong. I had to pay a mobile mechanic to install it since I was so busy getting a house ready to sell and he did a few things wrong. He used the wrong bolts in the wrong holes and overtightened and probably didn't use all the spacers correctly since he bent the ribs in the bed of my brand new truck. There wasn't much I could do about it after it was done. It was very hard to find someone willing to even do the install. After all of that, it has still performed flawlessly.


Super Pleased with etrailer's products AND personal service from their highly knowledgable staff! I went to a local hitch installation dealer where they attempted to find Item #RP50074-58 ( 5th wheel RAIL KIT for my new '19 F-250 SuperDuty). The installer tried numerous warehouses and distributors across the U.S. but no one had this part! He suggested that I do some further research via the internet on finding this part and wished me good luck IF I did. I began my search with no luck; the reasons being given me were due to the pandemic, few,( if any) people were working and even FEWER warehouses were stocking items! Just when I thought I had exhausted all search possibilities; I reached John H. at etrailer. He was extremely professional, knowledgable and helpful in assuring me that they did, IN FACT, have my part # IN STOCK AND could ship it IMMEDIATELY! Ordered it on the spot (Friday) and it arrived before noon on Monday! I'm EXTREMELY pleased w/ etrailer's quality products; their availability and the friendly service of their staff. John H. went above and beyond in making my purchase easy assuring me that my item would arrive as promised, complete w/ tracking info and a phone # w/ personal ext. if I had any further questions regarding my order. NOW.... how can ya beat THAT? ....YA CAN'T! Have done business w/ etrailer in the past and will definately continue to do so in the future.


The hitch install kit is a good product. It took about six hours to install because my installer had never put this kit on the new Ford with the aluminum box before and he wanted it to be right. There was some issues with the fit on the frame. Little things like welds not ground down and getting it to fit tight to the frame of the truck. He was able to fix all of the issues with out any problems. Just a little longer installation time is needed to insure a proper fit than we expected. Overall, a good product. I would buy this hitch installation kit again, and I do recommend it.


Process of installation was not complicated, you will need a second hand on the two bolt rails in the channel. Directions were good and the installation video helped out a great deal.

2017 Ford F-350 Super Duty

Great rail kit. Fairly simple install. The instructions are easy to follow. I did not have to remove spare or rear wheels to install. Only had to have helper for the two bolts in the third row. Hint, tape the u spacers to the long handle nut that goes inside the bed cross member. I did install rails in my previous truck (seventeen years ago) so I kind of knew what to expect. Frame brackets are a lot better now.

working as expected. should last my lifetime

2019 Ford F-250 Super Duty

The product is well built with good material my only problem is the installation instructions are poor

If you use the link below, you can see an install video that should fill in anything you werent clear about..
-- Etrailer Expert Mike L - 01/21/2019


Took a little time to receive this, due to supplier or just the new model of the truck. ( it did take a couple of months for the bed-bolt socket to become available before I could get the bed liner). Could not find a video for this product installed but the instructions were great and the install went smooth. I did remove the spare and rear wheels. No problems with wires or hoses and the only nut that was close to being hard to get to was driver side front and it was not bad. This was my first install of this type product and my hitch fits better than my previous truck that I had paid to install. Hooked up to my 30' camper, took for a test drive and I'm back in the camping business. Other than the wait, I can't imagine a better deal.


One rail has bow in it to where I have to use a jack to reinstall 5 th wheel, had it checked by dealer and was told holes where off where it comes through the bed

2018 Ford F-250 Super Duty

Installed the base rails for my 5th wheel hitch on my 2018 f250 sd without any problems, Instructions were very easy to understand. George at etrailer was very helpful in getting me to the right product.
Thank you etrailer

2019 Ford F-250 Super Duty

Would give this item 5 stars except the spacer blocks are extremely difficult to use in certain spots. If the brackets had a way to hold the block it would make the installation much easier and besides the spacer blocks it is easy to install and works great.


Easy install thanks to your install videos,Everything fit perfectly and is very high quality.

2017 Ford F-250 Super Duty

Great product! The custom Reese Quick-Install Rails and Installation Kit was as easy as advertised. Only drilling required was through the bed to install the rails. Two people would help the install for the driver side front bolt.


Reese 5th wheel hitch kit was heavy duty and assembled very well. Good company follow up and a good product for the money.


this was an easy install. if you have basic mechanic skills and the proper tools it was easy peasy.

Great i recently taken out and install in a new 2019 with all new hardware.

2018 Ford F-250 Super Duty

Excellent customer service! Fast delivery. This was my 2nd time shopping for 5th wheel hitch and rails. Extremely happy with your products and service. Highly recommend


Directions to install were easy to follow and fit as advertised. Only special tool needed was a torque wrench. Very happy with the product.


The information I received when I called was excellent. I placed the order and two days later the hitch was on my door step. All of the boxes were in good shape and everything appears to be complete. I will install the hitch this weekend and see how we make out. so far so good. Thank you for the great service.

2017 Ford F-350 Super Duty

Was a breeze to install, fit my 2017 F350 super duty perfect. Was not able to get the product locally but you guys had it in stock And they wonder why we use The Internet.
Thank’s again


I have installed a rail system in the past, but was surprised by this one. It's plug and play with pre drilled holes that match your vehicle for less drilling. High quality steel with all the accessories needed to complete the installation.
