I just picked up a used 7x16. It has an A/c unit in it and the previous owner used extension cords/generator to run it. I would like to wire the whole trailer properly so that it can run off a 12v deep cycle marine batter or a generator. I want to have outlets to run lights, the A/C and a Tv/ps3 for the kids. I am an electrical beginner at best. Is this something that is not difficult to do and if so, how? The trailer is split in 2 with the front living quaters and back garage. I want to get power to both ends. Any help would be greatly appreciated. I searched and didnt find anything specific. If its a big deal, I am not opposed to getting an electrician to do it, but what would something like that cost?
