Not off topic… these are apprehensions we all have when getting started.
Almost all floor rot comes from above, not below. Scamp
coats the bottom of the floor, so moisture from below is unlikely to be a problem.
Prevention means keeping windows
and vents sealed and dealing promptly with plumbing leaks
. Check windows
and vents every so often during heavy rains. Inspect inside the benches and cabinets near windows
when you do spring and fall
cleaning. To put it in perspective, my Scamp
is 7 years old, and so far, no leaks
anywhere. I do have one rivet that is allowing a slight seepage (due to my own failure to replace the plastic cover when needed), so I'll have to deal with that. No issues with windows, and I test them at least once a year with the pressure wand at a commercial car wash.
Mildew, more than rot, might be a problem in the NW when the trailer is stored for periods of time. There have been some discussions in past threads, but, honestly, I didn't pay too much attention since it's not a problem in my dry climate. I know there are solutions.
