Well, this weekend I am finally going to get the floor in the van. It came with an insulated mat backed soft floor covering which I will remove and use as a template for the new floor. First I plan to put down a layer of Reflectix with additional strips between the floor ribs. Next will be 3/8" plywood bolted to the floor, probably in 3 sections. Finally, as GreyDawg did, Allure Vinyl in "light bamboo". I will let this "float". I will take pics as I go along and post them.
