This week I have been building the subfloor with 1x3 furring strips, foam insulation, and 3/8" plywood. Supply chain issues and increased cost of materials has been a challenge but I am managing to find a middle ground.
The work has been slow but steady with some awkwardness maneuvering 4'x8' sheets alone but I have been enjoying the workout. That and it has been real hot and muggy here in Asheville.
My bus has two cutouts for the diesel tank and access to the engine. I am going to keep both accessible, which means some additional planning and cutting. I am very happy with how they are turning out.
I am wrapping up the subfloor tomorrow! I already have supplies for the next projects... :)
