So here is what I came up with. I'm going to load the camper today and hook up the trailer and see where it puts me. I may need to do some shimming, but I think it will be effective. When I'm unloaded I can loosen 2 bolts and slide them away from the rubber stops and tighten them there.

Looks like a good solution. The only concern is driving extended periods loaded, the bolts may loosen and cause shifting from constant pressure and movement. Good thing is you'd hear it if it comes loose. THUMP! Maybe weld tabs extending out either side and use a u-bolt from the bottom side up? Or figure out some kind of stop to prevent it from slipping all the way off.
