Nothing on a camper is metric, do far. You do need the square drive screw driver. A spare tire, and enough stuff to change it on the side of the road. Fuses, maybe, but if yo blow a fuse, replace it, and it blows again, then you need a lot more. I carry a lot of tools in the truck, and hope every trip I never have to get them out.
Bottom line, how much do you want to try and fix, or just give up and go home.?
