P Tuna is talking about my suggestion, and the OP is rather touchy. Then again he's talking about living inside a van.
Yes Tuna, the open-caell idea is going to fail the condensation test. In fact ANY insulation that is not itself a moisture barrier is going to become a moisture habitrail. I'm trying to think of something that would smooth out the obvious corrugations in the roof/upper wall treatment. Ensolite will do this, and is closed-cell.
IMO, the van presents certain unique challenges, IMO. #1 IMO the metal skin is highly conductive, and #2 IMO is doesn't breathe the way that metal siding can and does, IMO.
Again, IMO I think the OP's made good progress IMO and some sort of shot foam is called for in the lower areas IMO. I wouldn't mess with chunks IMO just fire away with the foam.
IMO.
haha you win the IMO battle, I concede.
