    I would like to put some kind of protective material on the underside of my camper floor to protect it from the elements. Right now it still looks like new, and I want to keep it that way. I was thinking of something like Flex Seal rubber coating of heavy rubber paint. Any suggestions?

    The manufacturers suggest that you do not seal the underside of a pup. You don't want to trap any potential moisture which will lead to rot or decay. It's best to leave it alone and let the underside dry naturally.

    What type of elements. Where I work, we have vehicles that travel in the surf extensively. The maintenance staff uses truck bed liner spray to protect the underneath from the salt water. That's the best thing they've discovwred - but it still only helps for a few years.

    Do not seal the underside of wood. It will trap moisture and promote rot.

    Good point. I was thinking of the metal parts of the chassis being coated for protection not the wood flooring.

    Guess I'll just leave it alone.

    Our first popup was a tiny, 1984 Palomino - not much ground clearance, so it got plenty of water and such tossed onto it as it was towed. The only water damaged there was in it when we renovated it in 2010 was from a leak from a taillight, which seeped under one dinette bench, in an out of the way place. We assume it stayed wet for a good long time; we were the third owner. Even the open hole where the drain from the ice box went through the floor didn't have much damage - and what it did have was probably as much from the drain vibrating in the hole on the road as anything else.
    When we sold it in 2012, the bottom of the floor still looked like it did when we bought it around the turn of the century, which was probably about the same as it did new. There was some rust on the metal frame parts though.

    I'd say that if it's 15 years old and still looks like new, then you're golden. Nothing needed.

    Yes, I think you're right. When I bought my PUP the owners said that was in mint condition. A likely story I thought. But it really was. Aside from one pin-hole size hole in the canvas near the door, there was not a thing that I had to replace or work on. The only repair work I've had to do since, has been to fix the little mistakes I made while learning to be a PUP owner. I blew the 60 amp fuse in the electric winch through my own fault. Everything else that I've done to it has been elective. I added electric brakes, a solar panel system, a new lift cable and up-down switch. I only replaced the cable because I didn't want to take a chance on it breaking while I was out in the boondocks by myself. Next, I want to replace the pump faucet with an electric on-demand type. I'll get to that in a month or so.
