This is exactly what I was looking for when I wanted to add the option of a fifth wheel hitch for towing. I don't do a lot of Fifth Wheel Towing. So the idea of a removable hitch what's important. The under bed rail system provided the opportunity to remove the hitch and still have full use of the truck bed when you're not towing. The video tutorial was great for helping figure out the installation. If you plan to do it yourself and you do not have a shop with a vehicle lift, plan on it taking two to three times longer. I was able to install it myself and my wife was able to help me with a few areas that needed an extra set of hands. I definitely recommend the under bed rail system if you need to be able to use your truck bed when you're not towing. There is not much to take a picture of since the under bed rail system is pretty much out of sight. The video tutorials and images on a trailer provide all the photos and images that you need.

Install was straight forward - quality of the unit was outstanding !!!

2009 Dodge Ram Pickup

Great product! I installed this myself in a few hours. Directions were clear, measured multiple times to ensure everything was square before drilling holes in the bed of the truck. Used cutting oil which was available in the plumbing section of local home improvement store when drilling the holes and helped a lot. Make sure you use the proper hole saw for cutting metal of course! I did slightly under-size the holes if I remember correctly. I believe the directions called for a 2 1/2" hole and I went 2 1/4"... given the spacing I'd re-evaluate and maybe look at 2 1/8" but regardless of the size hole being drilled, the install has been rock-solid. I've put about 1,500 miles on since the install and all is well.

2012 Dodge Ram Pickup

This is the second truck using the Signature Series Fifth wheel hitch. Had a Ram 05 2500 SLT, now installing on Ram 2012 Big Horn 3500 (not dually). both beds are long box. First time on the 05 took less the 4 hrs. Pretty simple, directions were good. This time not so smooth. Don't have the MEGA Cab but after wasting too much time trying to insert the rails(which I did on the first truck), just decided to follow the MEGA option and raise the truck bed. Also needed to remove the fender well cover on Driver side to access the area. Once I did this went pretty smooth. One ground lug had to be relocated which fell right in the middle of the plate on driver's side. Exhaust is always in the way for what you are about to do. Good idea to run all bolts into rails to clean out threads before install, especially the pointed locator bolt supplied. Also removed the spare tire and heat shield. Just do it, you will be thankful for the extra space.

2004 Dodge Ram Pickup

Installed in about 2 hours, works without adapter feet on my 2007 signature series 24k hitch. Did not install and remove rails to drill, just went slow with hole saw with rails installed. Foreward drivers side could not mark with punch sue to fuel tank so had to measure off other three. Fit around air bags and extra springs. Have used it once sonce install and seems solid.

One of the best purchasing experiences I have ever had. Steve helped me from the start by getting the right parts and keeping in contact every step of the way to make sure I was satisfied in the end. Fantastic customer service.

2003 Dodge Ram Pickup

This is an excellent product, all parts were correct. The install was challenging but was accomplished in the freezing cold of my driveway and it was the first fifth wheel hitch I ever installed thanks to the etrailer videos and instructions from the manufacturer's website.

2007 Dodge Ram Pickup

The hitch mount is great on its own merits. Easy to install and easy to use when switching out accessories. The service that etrailer has been phenomenal. I ordered the item with a deadline that it had to be delivered. They said they had it in stock but they were incorrect. They kept me in the loop and even expedited the shipping. Best price and customer service!

My experience was A++++++ from having Anna answer my questions regarding the Reese hitch to the follow up email form George to verify that my order came on time and I was happy. Great service ! I would definitely recommend and purchase from them again !

Ask the Experts about this Reese Fifth Wheel Installation Kit

  • Can the Under-Bed Rail Kit # RP30074 be Used with a PullRite SuperGlide on a 2012 Ram 3500
    If your PullRite SuperGlide 5th wheel hitch mounts to industry standard bed rails then you can install the Under-Bed Rail and Installation Kit # RP30074 on your 2012 Ram 3500 and then use the Adapter # RP30156 for a fit. This adapter provides attachment points that match any 5th wheel hitch that fits industry standard rails. Should you be doing any gooseneck towing in the future you may want to go with the Reese Elite Series Underbed Gooseneck Trailer Hitch # RP30158-52 instead. It combines...

  • How To Obtain Underbed Pucks for a 2012 Ram 3500
    The factory prep package was not offered on a Ram 2500 or Ram 3500 until 2013 therefore there would be no way to obtain this system on a 2012 no matter which bed you have. However, I can set you up with pucks using the Reese Elite Series and Signature Series Underbed Rail Kit part # RP30074. The puck spacing will be different for this system when compared to the above but this is your only option. The Reese Elite Series and Signature Series Underbed Rail Kit will then work with Ford...

  • Rubber Plugs to Cover Factory Puck System on 2017 Ram Truck
    For your 2017 Ram with the factory puck system, you will just need the Reese Rubber Hole Cover # RP30136 for the center gooseneck hitch ball location and the Draw-Tite Puck Plug # 58199 for the 5th wheel or safety chain locations. The Draw-Tite Puck Plugs include 2 covers, so you will want to order 2 to cover all 4 of the puck openings.

  • Recommended 5th Wheel Hitch and Custom Installation Kit for 2019 Ram 2500 That Leaves the Bed Clear
    I have a solution for you, but the Reese Under-Bed Rail and Installation Kit # RP30074 is not a fit for your 2019 Ram 2500 and there is not an aftermarket puck system available at this point in time for your truck.

  • Did Ram Change the Fifth Wheel Tow Prep Puck System for the 2020 Model Year
    The positioning of the factory fifth wheel installation pucks in your 2020 Ram 2500 has not changed since its inception. Side to side center to center, the pucks will be 39 inches apart. Front to back, center to center will measure 30-3/8 inches. In other words, a fifth wheel hitch that will fit the factory pucks on a 2018 Ram 2500 will also fit a 2020 model.

This kit uses brackets that bolt directly to the truck's frame, and drilling is required. The Reese Elite Under-Bed Mount you referenced, part # RP30074 is a fit for 2003-2013 Dodge Ram 3500 trucks and would not fit on your 1998 Ram.

  • Fifth Wheel Towing with 2013 Ram 3500 Equipped with Ramboxes
    You have heard correctly. The Sidewinder will move the pivot point between the hitch and the fifth wheel far enough to the rear so that the pin box won't hit the inside edges of the top of the bed side during turns. You could use a sliding hitch if you already have one, but you'll need to make sure that the hitch stays in the forward towing position at all times. The Sidewinder is specific to the pin box model, so you'll need to know which pin box you have. There should be a sticker...

For an excellent fifth wheel hitch confirmed to fit your rail kit we have the B and W Companion part # BWRVK3600. The Companion hitches are among the nicest on the market.

These newer Ram trucks with the factory prep can directly accept a specialized 5th wheel hitch such as the B&W # BWRVK3600 or the Curt # C16545-16021. Such hitches drop right into those factory pucks, allowing you to completely remove the hitch for a clear bed when necessary for cargo. Without seeing the...

    By the term, service body, do you mean a Cab & Chassis pick-up truck with tool box bed on the back? If so, you will not be able to install a fifth wheel hitch in the bed of the pickup due to the decreased width of the inside of the bed and the increased height of the bed sides, from the toolboxes.

If you measure the center to center distance of the pucks, and they come out to be 13 by 30 inches, they are Reese Elite rails that would be compatible with the Reese Elite 18K hitch # RP30142 or the 26.5K model, part # RP30871.

The 30067 will require drilling the truck frame and was made obsolete a while back.
