Teardrops n Tiny Travel Trailers

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

Sherwin williams exterior house paint on top of armor coat porch and floor paint. But the canvass delaminated from the wood, thats why the paint cracked...

It let loose due to too much movement. You have 2 unsupported boxes right now that can flex entirely too much. Then you forced it all to flex even more for transport. All the cracks are at joints because thats where it can move the most.

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.

Sorry , no way we can see those TOO BIG a photos …

Did you use the reinforcing strips along the joins as we originally suggested … ?

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.
Pretty sure nothing i have done here is new.
And i only have myself to blame for not building with plywood, being done last year and camping this year.

Plywood … 57lb/ cu. ft. Foam 2lb/cu.ft. 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 … ?

Sure, but my walls are .87cuft per linear foot and plywood would have been .146.
Plus the wood i had to add, canvass, glue, 75pounds of paint... all adds up. Since i started i have discovered that aerodynamics matters far, far more than weight.
I dont exactly have a camera with less megapixels to go take a photo with. No issues viewing it on my phone, my normal issue on a computer is photos are too small so i have to right click and open them in another tab. Not sure if thats works for large ones but if not i guess im done with photos. Photobucket killed all my previous ones and imgur is a huge pain to use.
Yes i know canvass sticks quite well to wood. Its been stuck on there for 8 months and 2 previous trips like what i just did. Only difference this time is it was probably fully dried and i strapped it tighter and had a brace fall out just over an hour into my hour and a half drive with it.
I used tb2 thinned less than 5%

Curious ??? Wish I lived closer to see it uo close.

75 # of Paint …

GPW, try using your Ctrl and - (minus sign) keys together. I was able to zoom out and see the oversize pics.

Nothing too scary.

75lbs of paint, how???

Well its 10-11 pounds per gallon, thats only 7 gallons. Maybe that was only the top half that took 70 pounds, lol. I cant remember. But pmf takes a ton of paint and i have a lot of square footage.

Dan, is that BEFORE it’s dry ? Acrylic paint does lose weight as the solvent ( water) evaporates .

KC, Thanks , I was anxious to have a look .

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 …

Yes, i mentioned all the weights of different parts of this trailer in post #29. The sherwin williams paint is only half solids but the porch and floor paint had a much higher solids content.

Yes, i thought i had made it more clear in that post you quoted, but i know the cracking is from strapping it down. I figured this was more common, the straps never touched the foam, just went over top of the 2x2 uprights of the frame. Paint cracked at the joints of the 2x2's. Isnt it more common that people need to move their foam builds in the year or 2 they spend working on them?
The canvass delaminated so i think ill do what tigris said below and inject glue underneath. It may not dry because of the paint though... :/

So here are some photos. Made water tank brackets, welded on those jacks, brought the lower half back to where i work on the trailer, then bolted it down last night.
However i have a new problem. The trailer frame bows down at the back. I put the 4 corners of the trailer on jackstands to drill the holes through the box and bolt it down. When the bolts were tight the top of my door opening was 1/8inch narrower than the bottom. But when i took the jackstands out the frame pulled back down a bit and because its not supported all the way across the back the top of the door opening is now 1inch narrower than the bottom :/
Last photo is of it bolted down.
