Thanks for that info, Jay. And thanks, everyone, for the ideas on the wires. I like that pipe insulation idea, Dale, especially since I have gobs of the stuff at home from redoing my plumbing. I've got the west coast mirrors on my truck, which really helps with the towing and backing, although backing really is easier with a 2nd person.
The trailer itself is a 24', V nose, 5200# torsion axles for a 10,000# GTW (trailer weighs 3700#), optional aluminum 15" wheels. Along with the obvious visible options, I optioned a couple of things you cant see, like roof bows every 16" with full insulation top and sides (to stop the top from vibrating, which can lead to leaks). It also has 120 electric with lights and outlets, 2 spare tire wells and 2 winch plates, one for the winch and one for the center pulley system I installed. I'm also adding a battery system in the trailer for the winch, one that's recharged by the trucks alternator system.
