Hello all! I've recently begun a long-dreamt-of project to convert a van to a camper - I found a 2002 VW LT with a luton box body. I'm trying to do everything on a shoestring (my first go at doing it, so I don't want perfect, I want good-enough), so Freecycle and Gumtree have contributed much of the interior - including some click vinyl planks. I've so far laid a subfloor consisting of treated 2x1s glued to the van's phenolic ply base, with rough-cut expanded polystyrene insulation stuffed in between, aluminium foil tape covering this lot and then 18mm P5 tongue & groove laid on top, using tongue tite flooring screws (at the seams as instructed and then also directly through the board into the batten in some of the higher areas - although this hasn't reduced the height much). When I cut the insulation, some of it jutted out above the battens - I (perhaps foolishly) assumed it'd compress fairly well, however my chipboard isn't all flush to the battens. It's reasonably flat/even, but there are some areas with a gap of maybe 5-8mm (visible at the back end of the van), and some which are flat. The sub-base itself wasn't especially flat. I understand click vinyl needs a pretty flat floor, and I worry that mine might not be flat enough. What are my best (and cheapest/easiest to find free) options here? Underlay? Switch to carpet/tiles or sheet vinyl if possible? Walk around on it for a bit or leave some heavy stuff on it to compress the polystyrene? I appreciate the proper answer is probably to rip up the P5, lose the foil, recut the insulation and redo it all, but it was a lot of work! Would a pro think this is sh*t? Please critique my work
