So they said it couldn't be done...tow a 5th wheel with my RAM the way I have set up, short bed with RAMBOX. It was a challenge but I finally got it done. My setup is a Curt 16K Hitch CURT Manufacturing - CURT E16 5th Wheel Hitch w/ Rails #16116 with bed rails using the frame kit Search Results for 16426 and what really makes it work is using the Reese 5th Airborne Sidewinder 5th Airborne Premium 5th Wheel Air Ride King Pin w/ Sidewinder and Turret - 16,000 lbs Reese Fifth Wheel King Pin RP61452 I bought the Hitch and install kit off Amazon and got a great price on both. The Sidewinder I got from eTrailer. Very good to work with! I had the hitch installed yesterday by a shop close to me and they also installed a wiring kit Curt 5th Wheel/Gooseneck Custom Wiring Harness w/ 7-Pole Connector - 7' Long Curt Custom Fit Vehicle Wiring C56070 into the bed of my truck in a spot that did not affect the RAMBOX or the bed. I have a Bakflip bedcover and it fits perfect over the hitch. My neighbor and I installed the Sidewinder on my Arctic Fox 29-5E. All I can say is that it towed great going for a quick spin around the neighborhood. Tracked well and very easy to hook up and take down. I did have to modify the handle of the Curt Hitch as it had too much pull distance but that was easy, just drilled a new hold for attaching and then cut it back a couple inches. I will get the lock tab welded back on soon but for now good to go!. Hopefully this will help others that have a short bed with a RAMBOX setup that have been told it can't be done, well it can but you just have to work at it. The issue is only that you lose the area above the wheel wells but if you get a hitch that has a handle that either rotates or that can be modified you are good. I have a buddy who did the same thing but used a Demco 5th wheel hitch. You DO NOT want to get a slider hitch with the RAMBOX. If you only have a short bed you can use a slider or what I did the Sidewinder (which I think is much better). If you decide to go with the Curt Hitch be advised that Reese Sidewinder will NOT work with the new “Q” style, you must get the “E” style hitch. Has to do with the wedge that gets installed. Well hope this helps others with RAMBOX!
