I know a lot of folks have bought or are thinking of buying an old caper or rv to use in a bug out location. I have seen some real steals on craigslist but the pictures usually tell why it is such a steal. If you have one or have your eye on one you may like to check out this tutorial from Randy Godwin. He walks you through the process of replacing the floor from ripping out all the old to laying the new flooring. Turned out looking like brand new. It might be worth the effort if you have an old one or can get one cheap to do this work yourself.
