Solution for Towing Fifth Wheel Trailer In 2015 Ram Where Pin Box Hits Bed Rail Sides

Question:

I have a 2014 crusader 5th wheel trailer . I believe it has the Lippert 1621 pin box with the black plastic cover. If I lower my reese 5th wheel so the trailer sits level the plastic cover hits the trucks side rail. I thought of taking the plastic cover off the pin box but I think it will still hit.When I lower the 5th wheel the trailer has about a 7 inch clearance from the bed rails. I have not heard this problem before. If you have any suggestion that will help it will be appreciated. Thanks

Since your truck is a 2015 Ram 2500 this makes me think that you possibly have Ram Boxes which are notoriously known for not allowing a normal fifth wheel pin box to make tight turns. There is a pin box solution though.

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.

What you would need to do is replace your 1621 with the Sidewinder part # RP34FR and your fit issue would go away.
