Teardrops n Tiny Travel Trailers

Anyone looked at or used this? Not rated for exterior exposure but not sure that matters if PMFed or fiberglassed or otherwise skinned. I searched and found one reference regarding cleaning it.

I used revolution ply for wall construction on my build. I covered it with epoxy and fiberglass. It is a quality product, very stiff. I was unable to get it to bend on a 30 inch radius. I did call Patriot Timber and found that the glue used in its manufacture is waterproof.
