Well, after waiting a week or so for the ambient temps on Cape Cod to get above 60, finally I started this project.
Here's a shot of the prep work and the first few rows. Anything that is bolted or screwed to the floor (the co-pilot seat, the TV cabinet etc) are up on shims and the floor cut around it. I left 1/8" all the way around the perimeter. The idea is to get the entire floor to expand and contract as a unit.

The finished floor, minus the couch which will arrive early June. I guess we'll do our Assateague trip on the lawn chairs.



We'll see what happens and I'll report back next spring after a full set of seasons. It was less than $300 in material and about 20 hours of work, most of it prep.
