5th wheel with Rambox

[needgas__]

I have a 2015 Ram 2500 with a Rambox. Anyone pull a 5th wheel with this setup? Anything I need to know about hitch selection?

Most extended pin boxes are longer than 50% of the width between the rails of the Rambox. Your width is around 50" vs about 68" for a standard truck bed. So with any turn approaching 90 degrees, the back side of the pin box will hit the Rambox. If you switch to a short length pin box rather than an extended pin box, then you will not have sufficient clearance between the front cap and the rear of the cab.

The Sidewinder has it's own pivot that is 22" behind the king pin and a wedge that prevents rotation at the king pin. So, while it has the length of an extended pin box, it pivots more like a non-extended pin box. It does not swing in an arc that would cause contact with the Rambox.

You are correct it is the interior width of your bed that will cause a problem. The recommendation to use a sidewinder pin box is correct from what I have read with the ram box. You then need a hitch that will work with the sidewinder.

Here is a video with the Reese Revolution...same type of design as a sidewinder.

Best option is to use a Sidewinder pin box with a fixed position hitch of your choice. Otherwise the back of the pin box will hit the narrower side rails of the rambox. My utility bed is also narrow, but it sits lower so the pin box swings over the top of the bed sides.
