Your slideout floor is rotting right now. You just can't see it yet.
Most RV owners don't find out until it's a $3,000 repair.
It's just one sheet of OSB holding everything up.
Your walls, furniture, and floor covering all rest on a single 3/4" wood panel. No redundancy. No protection from the factory.
Water doesn't knock. It finds the screws.
Trim strips along your slide walls are fastened directly into that floor. Tiny caulk voids let water track down every fastener shaft — silently, for years.
By the time you smell mildew, it's already structural.
The factory plastic sheeting fails at fastener points. Water saturates the OSB from inside out. No visible signs until you step on a soft spot.
One floor replacement. One slide. $3,000+ Shops charge $25/sq ft. Full removal sometimes needs a forklift. That's before furniture, flooring, and reinstallation.
