If it was pre-wired, they didn't really do you any favors. All solar pre-wire is something like 10 gauge, which is too skinny to do you much good.

Our 2002 19' Bambi came with solar prewire. The wires are 10 gauge and are adequate for the size/number of panels you can fit on the roof. Here is a rational discussion about that: http://www.airforums.com/forums/f448...-a-163067.html.
