Thanks guys, very good info and very informative links. I now see the folly in adding solar panels to a vehicle, haha.
I think maybe if I do this, I might have to put some time into it. Maybe make it a project over a year or two, because 8 to 12k just isn't in my budget. If it was closer to about 4k I could swing it probably. I'll have to play with the numbers and look and see whats out there.
Well, that was just the info I was looking for, If I do end up deciding to build one, I'll be sure to start a thread... but at this point, I'd probably have to attend a lot of funerals if I told you to hold your breath.
