This will look totally the opposite to what I mean, but I had half an idea about boarding a van out to use for stealth camping on occasions, and having somewhere to sling the bikes, but the detail you're going to has started to put me off, as what I would do would feel very shabby in comparison.
I do hope you take that as the positive compliment it's meant.
EDIT: And thanks for sharing, it's really interesting to follow your progress.
Honestly I'd be doing the same but for two details. Firstly my wife caught wind of what I was up to and decided she might like to use it for an upcoming festival she's attending with a friend, which raised the finish level required for the interior Secondly, I'm well known for over engineering things out of sheer boredom. You should absolutely go ahead with your plans, you'll have a great time making and using it Some of the best micro campers I've seen have been made out of old pallets!
