Found one dampish corner in the van. No mould, just a bit moist. Dried it yesterday and it's fine today. One cam on the rear window there wasn't closed and the Southcoast had that load of raIn the other week. So far in 3 days we've pulled less than 1ltr. Thats with the gaffertaped window too.
The van smells dry, I can see the beauty of the monocoque habitation build. Bondrite gear arrives this afternoon so I'll have a crack at the window removal and repair tomorrow. Bricking it tbh!
