I have a solution for you, but the problem with the Ram Box is that is that it puts the rails of the bed too close together and it causes interference with the pin box of the trailer around corners.

We have heard several customers say that with a Sidewinder pin box they were able to tow a fifth wheel trailer with a truck with a Ram Box. Sidewinders move the pivot point higher so the Ram Box wouldn't interfere.

The only problem is that Sidewinder hasn't officially said that you can use a Sidewinder with a truck with a Ram Box without interference. That being said we do know this is a solution that works.

To recommend the correct sidewinder for your needs, I will need to know the brand and model number of the pin box to recommend a replacement sidewinder. Usually the trailer's pin pox has this specific information on the nose of the trailer or you will have to find out from the dealer. I have linked the Sidewinder information for you to check out as well. There is a chart at this link that shows all of the corresponding Sidewinders based on pin box model/number.

For a rail kit you would want a custom fit kit like the part # RP50054-58 which will minimize drilling and install time. For a hitch then that will give you excellent king pin contact you would want the part # RP30928. The correct Sidewinder wedge for this hitch is part # SWW-01.
