How Can I Gain More Bed Clearance with My Demco Autoslide 5th Wheel Hitch?

Updated 06/22/2026 | Published 06/15/2026

Question:

I have a 2024 Sportek 36VBH with a 2026 Ram 3500 Dually with auto level. My pin box is standard with morryde king pin. I’m using the factory puck system. My hitch is Demco Autoslide 21k. Currently my hitch is in the low position. I can see one set of holes at the top of my pin box. Trailer and truck is level. My problem is the back of the pin box brackets are at the same height or slightly lower than my box sides. In a turn they will hit. From the rail to the underside of the camper is about 6”. What do I adjust to get clearance?

Hello Daniel,

Thanks for including the pictures, always most helpful!

I reached out to Demco to confirm, and it sounds like you did as well. Demco confirmed that raising the hitch head one position on your Demco Autoslide 5th Wheel Hitch w/ Slider for Ram Prep Package - 21K # DM89GV is the correct adjustment to make.

Based on the measurements you provided, your trailer is already towing level, but moving the hitch up one notch will give you additional clearance between the pin box brackets and the bed rails. That should help eliminate the concern about the brackets contacting the bed sides during tighter turns while still maintaining a level towing setup.

It sounds like you've done a great job getting everything dialed in, and this should be the final adjustment needed to give you a little extra peace of mind on the road.

Once you get the new Autoslide set up and ready to go, where are you headed for your first trip?
