I ordered and picked up my trailer last year but it’s a lot smaller than the one you are looking for (26 footer). I had it wire for a stereo with four speakers and out side antenna. Then I wired in my stereo. I had a mouse hole installed for a winch and put mine in. Garment closet worked out very nice because a 30 gallon fuel barrofits perfect with lots of extra room. Inside light and extra electrical outlets. One electrical outlet up front outside. Two quarts 500 watt lights which I later bought led lights for. Rubber coin floor then I mounted diamond plates where the tires sit. 16 inch wheels and tires. Smooth side no rivets. 4 foot side door. Workbench and I wired in an inverter.
