Enclosed trailer extras

I installed 2 inside/outside 110-volt receptacles in the front-left and right-rear corners of mine. The front powers my battery tender, and the rear one is for a battery charger/tender, for use on a car..if stored in the trailer. I need a chock for my scooter and a fuel jug rack. I don't think I've used my generator or A/C, more than a half-dozen times.
