Fifth Wheel Hitch Setup for 2020 Ram 2500 Mega Cab with Ram Boxes

Question

Question:

For all cab styles of the 2020 Ram 2500 that have the Ram Boxes the only solution to tow a fifth wheel trailer is with the Sidewinder pin box replacement as it moves the pivot point up high enough not to interfere with the narrower bed rails of the Ram Boxes. You'd need a fixed hitch like the part # RP30047 with a custom rail kit for your truck like the Curt # C16427-204 which fits your truck and the Reese hitch. Sidewinders are pin box specific so you will first need to know what pin box you have now in order to pick out the correct one. There should be a sticker or a stamping on the OEM pin box of the trailer that will list the pin box number that is on the trailer. Once you figure out which pin box you have you can check the FAQ I attached that has a chart that shows the correct Sidewinder to get based on which pin box you have.

The problem is that even the taller hitches don't move the pin box up high enough to prevent interference with the Ram Boxes around corners. Plus you have to consider you can't continue to raise the hitch up as the trailer needs to sit level. Although the pivot point is moved back the attachment to the vehicle is still above the truck's rear axle so there is no cause for concern about sway like with bumper pull trailers.
