2006 Dodge Ram Pickup - Reese Quick-Install Custom Outboard Installation Kit w/ Base Rails for 5th Wheel Trailer Hitches

Reese's outboard installation kit for your fifth-wheel trailer hitch was designed with safety and convenience in mind. Just like the original custom mounting brackets, these brackets install using existing holes in the truck frame, minimizing installation time. The biggest difference with this outboard kit is the extended-length rails. These above-bed rails are 5 inches longer than standard, universal fifth-wheel rails so that they will match up with the mounting points on the brackets, which sit below the bed and outside of your truck's frame. The result is a much simpler installation process, wherein most underbed components can be easily avoided. Because you are working outside the frame rails, you also have easier access with your tools and more room to work, making the whole process less of a pain.

The base rails included in this installation kit feature a standard 10-bolt design. Each of these rails attaches to the underbed brackets with two carriage bolts at both ends. A single bolt is used in the center of each rail to further secure it in your truck bed. The result is a set of base rails that remains firmly in place thanks to 10 points of contact.

This entire installation kit is built to be SAE J2638 compliant and has been extensively tested per specified accelerated-life-cycle criteria for fifth-wheel trailer hitches. The requirements for testing are based on the European-style test of 900,000 cycles, making this testing process among the most thorough and intensive in the industry.

Ordered this hitch for my 03 ram 3500 shortbed and didnt get a chance to install it untill 2 months later. Which is when i noticed it was missing some hardware. I contacted etrailer and they shipped me the missing hardware at no cost to me, how can you beat that anyone else would have said go pound salt its been 2months . The installation was cut and dry with good instructions. I like how the hitch installed onto the frame and the quality of the parts its built heavy, its agriculture approved lol. Thanks again etrailer for the unbeatable price and fantastic customer service

2006 Dodge Ram Pickup

This kit was pretty easy to install. Took 2 guys about an hour and a half to complete. The install video was extremely helpful. We watched it several times before we began. Everything fit like a glove and looks great. Will definitely buy this kit on my next truck. The hardest part was cutting the flimsy bed liner. Thanks Reece and Etrailer.

2008 Dodge Ram Pickup

Instructions were great & installation was easy. High quality parts that looked great and are holding up well. Etrailer and Cequent (Reese's parent co.) are both great companies to deal with - extremely knowledgeable and helpful with the products they sell.


I installed this rail kit in about 4 1/2 hours including cutting out the bedliner. The instructions were perfect. It fit great. The staff at e trailer led me to this model kit and I'm glad they did. Great product


We got off on a rocky start because the parts weren't correct in the box but that wasn't etrailer's fault.. Etrailer went above and beyond to correct the problem and I greatly appreciate it.. product fits great and I'm very pleased. Fair price also.. Will do business with etrailer again


Fantastic product and service. This was exactly what I needed and it arrived on time and in perfect working order. You guys ROCK!


Great kit the you tube video was very h elpful

  • Recommended 5th Wheel Base Rails for 2013 Ram 2500 Short Bed
    Without seeing the hitch in question or knowing the exact model, it's hard to say with confidence what kind of deal it is, however the price you mentioned is going to be hard to beat if it is in fact barely used and in good condition. You did mention though, that you were told that it was an "auto slide" hitch from Reese. Reese does not currently produce an automatically sliding fifth wheel hitch, so most likely you are looking at a manual slider (unless the seller misspoke when he said...

  • Fifth Wheel Towing Using 2013 Dodge Ram Short Bed w/ Ramboxes
    Reese's official stance on the matter is that Dodge Ram trucks equipped with the Ramboxes can't be used for fifth wheel towing. The Ramboxes make the inside dimension of the bed narrower than usual, so the fifth wheel pin box will very likely strike the inside of the bed rails. They have had customer reports that using a Sidewinder makes fifth wheel towing possible by moving the pivot point far enough rearward (22 inches). My Reese representative tells me that they have not tested a fifth...

  • Sidewinder Recommendation to Allow a 2013 Ram 2500 with Rambox to Tow Fifth Wheel Trailer
    We have heard customers who have installed 5th wheel hitches in Rambox models. But they have to use Sidewinder replacement pin boxes to move the trailer pivot point up above the bed rails so as not to hit the stock pin box against the bed sides. I have linked the Sidewinder information page to the right. You would have to replace the pin box of your trailer with the Sidewinder. If you can find out the pin box model you have at the chart that is at the attached link you will be able to...

  • Easier to Install Fifth Wheel Rail Kit Recommendation for 2010 Dodge Ram
    Outboard fifth wheel brackets are much easier to install than the inboard ones like what you have and are trying to install on your 2010 Dodge Ram short bed. Since the rails and brackets are both different in design you would have to go with new rails and brackets. For that you would want the outboard kit part # RP56011-53 which is a confirmed fit for your 2010 Dodge Ram. The rails are slightly taller but will be much easier to install. This rail kit will be compatible with the Curt hitch...

  • 5th Wheel Trailer Hitch Installation Kit for a 2012 Dodge 3500 Dually with 8 Foot Bed
    Yes, for your Reese 20K # RP30928 and your 2012 Dodge Ram 3500, you can use custom installation kit # RP56011-53. This is a custom kit which means it requires little drilling and installs faster than the universal kits. Installation time is estimated at 2 hours but realistically if you have not done it before it will probably take a little longer.

  • Can Dodge Ram 2500 with Ram Boxes Tow Fifth Wheel Trailer
    The problem with the Ram Box is that is that it puts the rails of the bed too close together and it causes interference with the pin box of the trailer around corners. We have heard several customers say that with a Sidewinder pin box they were able to tow a fifth wheel trailer with a truck with a Ram Box. Sidewinders move the pivot point higher so the Ram Box wouldn't interfere. You will need to remove the pin box of the trailer and replace it with a Sidewinder pin box. Sidewinders are...

  • RBW Lil Rocker is Not Fitting in Reese 5th Wheel Installation Kit # RP56011-53
    The only things that are different between the rails in kit # RP56011-53 and the regular rails is that the -53 rails are longer overall and the tops are a bit wider. The spacing for the hitch feet is still the same. There are 3 sets of mounting slots. The inner set is 10 inches apart on center, the middle set is 20-1/2 inches apart on center, and the outer set is 29 inches apart on center. Front to back they should be 22 inches apart on center. The other difference is the width. The top,...

    The Reese # RP30033 5th wheel hitch you referenced is indeed compatible with the industry standard fifth wheel rails, and given the description of the fifth wheel you mentioned, a hitch of this type would be perfect for your needs. The hitch has plenty of capacity to spare, which would be great if you upgrade to a heavier trailer in the future. The hitch also includes the wiring harness w/ 7-way trailer connector that mounts through the sidewall in the truck bed. You would also need the...

  • What is Difference Between Reese Fifth Wheel Rail Kits that Fit 2008 Dodge Ram 2500
    Reese makes two different styles of above bed fifth wheel rail kits like you mentioned that have pros and cons. The Reese Rail Kit part # RP50140-58 is an inboard rail kit which means the brackets install too the inside of the truck frame and not the outside. This has advantage of having rails that are a little shorter in height and in length. These kits generally cost a little less too. The Outboard Rail Kit part # RP56011-53 has the big advantage of having an easier install since the...

  • Fifth Wheel Towing Using 2013 Dodge Ram 2500 Short Bed w/ Ramboxes
    Reese does not recommend fifth wheel towing with Rambox-equipped Ram trucks. The Rambox makes the bed too narrow, so there is a real danger that the sides of the pin box will impact the bed sides during turns. There have been reports that using a Sidewinder will produce enough clearance that this danger is removed, but Reese hasn't tested it and therefore cannot recommend it. If you decide to try it, you'll be doing so at your own risk. The # RP56011-53 install kit would work fine, but...

  • 5th Wheel Trailer Hitch Installation Kit for a 2013 Dodge Ram 2500 Long Bed and Reese Hitch
    5th wheel trailer hitch installation kit # RP56011-53 will fit your 2013 Ram 2500 long bed provided it does not have the OEM 5th wheel prep package. It will also accept the 20K Reese 5th wheel trailer hitch # RP30928. If your truck does have the OEM 5th wheel prep package with the underbed installation kit and 4 pucks in the bed then you would can use the # RP30918 which will drop into your puck system with no adapters needed.

  • 5th Wheel Trailer Hitch Install Bracket Kit Confirmed to Fit a 2011 Ram 2500
    The Reese Fifth Wheel Brackets # RP58522 are for newer Rams than your 2011 2500. The correct brackets for your truck are # RP50140 or for an easier install use # RP56011. The latter installs on the outside of the frame making it easier to access. If you need the base rails as well you can get the entire kit using # RP50140-58 or # RP56011-53.

  • Can I Tow a Fifth Wheel Trailer with My 2012 Ram 2500 with Rambox
    There is an option to tow a fifth wheel trailer with your 2012 Ram 2500 6 Foot Bed with Rambox. The issue with using a fifth wheel trailer hitch with a Rambox is your truck's bed is thinner. Therefore taking away clearance you will need for your trailer to make turns. The way to gain this clearance is with a Sidewinder. A Sidewinder gives you more clearance by moving the pivot point of your fifth wheel closer to the tailgate of your truck. Since it takes over as the pivot point the...

    I spoke with my contact at Reese who said that the load assist air bags on your 2012 Ram 2500 should be aftermarket.
