See http://www.youtube.com/watch?v=Orn7xAEKov4Re: Step one. Bought the van.I'd suggest acid-proofing the interior of your battery box setup. A leak from the bottom of a battery, or a spill will render all of your craftmanship (and the floor of the van) kind of holey quickRe: Step one. Bought the van.For sealing holes, especially when drilling them in the roof, 3M makes a great sealant that is a little expensive but worth it. It's been long enough since I put the two solar panels on my van that I forget the product info. Do a search with 3M for automotive projects and look for the sealant they prescribe for between fenders and body, etc. Good luck.
