I will get the lock tab welded back on soon but for now good to go!. 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. Tracked well and very easy to hook up and take down. All I can say is that it towed great going for a quick spin around the neighborhood. My neighbor and I installed the Sidewinder on my Arctic Fox 29-5E. I have a Bakflip bedcover and it fits perfect over the hitch. 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.
My setup is a Curt 16K Hitch CURT Manufacturing - CURT E16 5th Wheel Hitch w/ Rails #16116 with bed rails using the frame kit 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. It was a challenge but I finally got it done. 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.
