Most Popular Demco for 2018 GMC Sierra 3500

It's pretty heavy at 300 pounds. I had to rig a hoist so that I could install or remove from the truck. I installed the side plates first and had to adjust one of the locking tabs per the instructions. I installed the plates in the truck and then lifted the hitch assembly into place. After bolting hitch to the side plates, two of the locks on one side are too tight to remove. I'm going to drive around a bit before removing the whole assembly and adjusting the shims on one side.

Bolted directly to GMC’s factory 5th wheel prep. Nice to have the auto slide feature. No need stop, unlock slide, move the truck forward, re-lock just to make a tighter turn.
