I first designed and did built-ins for a Ford minivan. I found it to be too tight with a dog and a fairly regular job! Then the head gasket blew out on New Year's Day. Took me several months to find another. Just bought a Chevy Express conversion which is really nice because I can stand up in it! Just now removing seats, etc. Problem is I have 2 solar panels mounted into a wooden frame that was formerly attached to my Ford roof rack. With this curvy fiberglass conversion top, I am having an extremely difficult time finding the best way to get my panels up there securely! And it is a MUST DO! No matter what idea I come up with, there is some obstacle because of the way the roof is designed or the shape of the ceiling on the inside or all the racks are too short or the gutter clamps are reviewed as insecure, etc. I'm hoping someone can steer me in the right direction before I lose my mind!
