After putting the van and top up for sale in order to potentially get into a QuadraVan, I have started on the project again - the QuadraVan owner didn't seem extremely committed to selling it, which is totally okay.
Last week I convinced my brother to help me get the top into the garage so that disassembly could begin. It was just the two of us and with the metal roof of the previous van being still attached, it was a huge effort to lift it above waist level.
There were some minor injuries in the process, but it mostly went well!
Then I began breaking the top down so that I can get to work on the fiberglass, overall it seems to be in pretty good condition. I plan on installing an RV fan and LEDs in the ceiling as well as some side mounts for some gutter Yakima mounts for future solar panels. Then onto bedlining the top.
