Hardwood flooring can be expensive and many times not very good quality. This method cuts down on cost and weight and if you damage the floor you an easily replace a piece. Many people in vans put a sub floor then hardwood/ laminate etc. I used 3/4 inch thick plywood in 5.5 inch strips. I did a light sanding and clear coat. I might stain later. we will see how it holds up etc…I will try to update in a few years if possible.
