What kind of paint did you use? It cracked at joints due to flex and yes water will get past it.

You know , backyard engineering is a curious thing …. If you follow others lead and something goes wrong , you can blame them , but if you do it all by only what you think , you only have yourself to blame …

Yes you could have built with plywood … And when the paint cracked it would rot the wood underneath and delaminate the ply … If a foamie leaks , nothings rots , except all the wood you used … Foam doesn’t … Don’t believe me , prove it to yourself … Apologies , I don’t mean to be Critical , it’s just you’ve come so far , and now a minor problem shouldn’t set you back …
Sorry we couldn’t view your pictures … Just TOO BIG … posting too big a pictures , doesn’t do anybody any good … If we can’t see what actually happened , we can’t suggest a cure … but I’d suggest if the canvas didn’t stick to the wood , you did something WRONG …. Canvas sticks to wood better than it does to Foam , ( using wood glue ) What did you use … ?

KC, Thanks , I was anxious to have a look .
GPW wrote:Saw the pics ( Thanks KC) … not so bad ! Read this : “ I strapped the box to the frame and towed it to where i work to bolt it down “ Makes me wonder if the straps did this ? We don’t strap foam !!!
I’d just rub a little primer on those , give it a paint touch up and be on my way …

I would wait until the rest of the trailer is about done so those walls are correctly supported then paint over those. Possibly inject some glue under the canvas first and press it to help it re-adhere.
