I just bought a 1955
Overlander and the PO put down Flor tiles over the existing peel and stick tiles. from the few spots that I've inspected that typically have water damage, there is staining but no rot. (keeping fingers crossed) Eventually I'd like to replace the carpet with something a bit more water/stain friendly, as I'm now a full-timer, but have to admit, the Flor tiles are pretty cozy, and super easy. They may just stay as I do everything else needed that comes with a vintage rig. Looking forward to seeing what you choose!
