Ha! That's pretty great. Like what you did with the sink. Do you plan to do some heavier insulation on the roof? That's where the sun really beats down and brings heat into the van -- that and the radiant heat coming through the windshield. I've been vanlifing for a couple years ... so these are the first things I think about... lol.
We were actually still considering what to do about the roof. Do you have any specific tips for this situation? I really wanted to keep maximum head space but I think ceiling insulation of some type would help immensely. We do have a cut Reflectix panel to reflect rays for the windshield and for both front windows so that's covered pretty much.
