Teardrops n Tiny Travel Trailers

has anyone tried to put a rubber shower liner or pond liner between the trailer frame and the plywood floor ???

Sounds like it would work, but why?. Roof tar would work just fine, and is a fraction of the cost.

In my view a vapor barrier like you are suggesting will promote rot if any moisture gets trapped between the rubber and the wood. For this reason I think a spray on or paint on coating or tar iwill serve better.

A lot of travel trailer manufacturers wrap their plywood floor in a sheet of nylon reinforced plastic. I have found that it is a great place to trap water in the few trailers I have had experience with. Leaky doors or windows, the water gets trapped in the plastic sheet under the floor. Leaking sink or shower drains, again the plastic sheet can catch and hold the water. It always leads to the floor delaminating. I like the way most tear droppers do it better. Some use epoxy, others use a roof coating, while some just use paint. My plywood floor was encapsulated in epoxy.

Like others mentioned, it's a great water trap. You live in AZ...I wouldn't worry about it. I'm in No. Cal. I just use a good quality oil based primer and paint. Others may disagree, but it works for me. Doug

I didn't want all that gooey roofing tar on the bottom of my trailer so I am coating it with an asphalt based fence post paint. It smells like asphalt when painted on but once it dries the smell goes away. Best of all it dries hard.

We sealed our TD (waterproofed) with our favorite mixture of 25% Polyurethane and 75% mineral spirits... a couple coats really sinks in and seals the ply/lumber...cheap and quick too ... Still use the tar stuff on the bottom though...

I used automotive spray undercoating 5 spray cans was all it took. Quick and neat.
