I have just purchased a 2011 Scamp 13'er

How do I keep the floor dry and keep it from absorbing moisture? Should I rubberize undercoat or use fluid film?

Hi, Bill - I've moved your post from "for sale" to "Problem Solving," in hopes that someone with direct experience will be more likely to see it and give you some guidance.

The underside of the floor is resin coated and doesn't need a thing. There's Scamp trailers on the road that are 40+ years old without floor problems. Damaging moisture comes in from the top, not from the bottom.

I agree with Byron that the bottom side is not the source of floor rot, though I have painted the bottom of my floor white just because to me it looks nicer. (I know that I'm the only one that sees it.)

I wish the top side had been painted or resin coated. Where ever I can I've used a can of spray paint to paint the top side, like inside cabinets and part of the floor under the dinette.

We had a pipe connection fail one night and water came shooting out. We cleaned it up quickly but there was a real difference between the painted areas where water just sat on top of the paint and the unpainted spots where the floor started to absorb the water. We took a hair dryer to the unpainted sections to completely dry it.

When we eventually get new carpeting, it's my plan to paint the whole thing before carpeting.

I agree with trying to make the top as water tight as possible. It would seem to me that some diluted fiberglass resin (sort of home made GitRot) would be a good top coat.
