Re: Flooring Materials...
I would not use sheet aluminum as the final exposed floor finish. It will over time loose it finish and you will have grey socks fast if you take your boots off in the van. It will also scratch pretty easily and is pretty loud to walk on and does not help absorb road noise. Dogs will not like it - no grip. Rhyno liner would be an improvement for durability but can have a long term odor.
