I bought this lovely fixer upper on craigslist, it is a 1963 Globe Trotter as far as I can tell from other pictures of like trailers. I would love words of wisdom from others that have started and or completed full interior restorations. The floor is rotted the shower is sinking and whoever had it last smoked. Any ideas on how to clean without damaging the original interior paint? Is there a way not to take the body apart and replace the floor? Thanks for any help.... and to people living close...
