The tiny camper stays outside all the time and spent last winter without a tarp. We are camping next week.

I also recently discovered Revolution Ply. I had forgotten about it then came across some at a Lowe's store. It looked like just what I need for the exterior of my tiny travel trailer. About 5MM thick, uniform and priced at about $16 a panel. I don't see anywhere on the manufacturers website where it is expressly forbidden to use outdoors, but it was labeled that way at the store. Sounds to me like the experience with builders here regarding it holding up to moisture has been good.
I don't like the idea that the surface may appear indented in some areas. Not sure if you can see this in the store and avoid those panels.
17 years ago I built a sailboat from luaun underlayment encapsulated in epoxy. Cheap stuff. It has spent its whole life outdoors (including MN winters) and other than a new coat of latex paint every 3-4 years it is holding up incredibly well. My build budget has taken a big hit and if it is a choice between not building and trying alternative materials I am ready to give that stuff a try for the exterior of my ply/foam/panelling sandwich construction with 1 X framing. Might use
The Mix to seal it instead of epoxy to save cost, but I am a little skeptical about how well latex paint sticks to wood treated with paint thinner. Or I might just go to the local lumberyard and see if they have 1/4" ACX plywood that isn't all warped and junk like I keep seeing at the big box stores.....
It is always nice to be able to get real world opinions on this forum!
