Thanks for the positive comments. For the headliner I used a 3/8 radius and used 3M 77 to mount it. Don’t know why anyone would use contact cement… My electrical system is all 12v, but I did put a 110 outlet inside and one in the galley. The wheels on the trailer are still 12″, I just upgraded to a high speed radial tire and the nice looking aluminum wheels. The only other suggestion on the Northern trailer is to repack the original bearings. Probably wouldn’t have to, but you never know… The galley flat and shelf are covered with a rubber floor runner I found at Menards. It’s about an 1/8 inch thick and comes in a 30″ width. Just suggest you make a cardboard pattern first.
