FLOORING
When we bought the van, it came with a protective vinyl floor matting. We decided to keep it & once the floor was insulated we would put it back, then lay a timber floor on top.
We figured the more insulation/protection on the floor the better!
We did have to customise the floor matting a tad, so it would fit back in, around the insulated wheel wells and bed legs.
For the flooring we chose a 6mm Oriented Strand Board. This was mostly due to how it looked and the fabulous texture.
We secured the sheets of OSB to the floor using the existing anchor point bolts and bolt holes.
I applied 3 layers of a clear, satin finish waterproofing/ protectant.
