Same here. Our box truck has hardwood flooring and was used as a work truck before we bought it. We carry two bikes in the back and camp in it once the bikes are unloaded. On one trip one of the bikes leaked gas which soaked into the floor. The fumes were terrible although it was a small spill. It took all day with fans and repeated scrubbings with Dawn detergent to get it to the point that we could sleep in the back. Since then I have coated the floors with multiple coats of polyurethane which makes cleanup much quicker. I also cut a door through the bulkhead that separated the cab from the box. The door is fully gasketed and can be lifted off the hinges and moved to the side once the bikes are unloaded.
