Teardrops n Tiny Travel Trailers

Hey Y’all!
I have been reading tons and have finally half-way convinced hubby that this will work.
We started to build about a month ago.
Hubby found this, for free. (Sorry its fuzzy)



We built the floor using 2 x 3’s and ply. I coated the ply with “the mix”.
I started trying to get the foil off the foam. I ended up sanding the foil off of the sheets of foam.
Then we attached the walls.



The plan was to attach the roof and canvas this weekend.
Then Mother Nature changed the plans.



I am sorta glad it collapsed, I can now see that the foam edge was not level/straight so the edge of the floor and the walls did not make good contact. Next time I will use Great Stuff instead of Gorilla Glue.
So now I am back to square one, but I hope I can make corrections and make the camper better in the long run.

Now I have a question.
As you can see in this picture there are holes in the foam.



Do I need to fill them and if so with what?
I thought about using light weight drywall spackle. Hubby says to use Great Stuff.

Spackle !!! GS will keep expanding ending up with bumps instead of holes .. messy too !!!

What kind of foam is that ???

Thanks GPW. I was thinking the same thing.

I think the foam in polyiso. There are no marking on it to tell me. 2 inch thick.

Hubby found it at a landfill and it came to our house.

Is it brownish (tan) and sorta’ crumbly ... ?

that looks like polyiso/polyure board. Just becareful.. it off gases CFC's and HFCF's which are dangerous to breath and to be in skin contact with

Maybe that’s why it was in the landfill ...

GPW It is a very light tan, almost a cream color. Crumbly? Not sure what you mean but when cut it beads up like styrofoam, but smooths just rubbing it either by hand or by sanding.

JThompson Can you explain a little more about the off gassing? You now have me rethinking about this and need some more information.

The reason I say it is polyiso is that I bought a piece of ployiso at the big blue store for a different project. The 2 look similar, but not exact twins.

Maybe if there’s some printing on it you can better identify it ... ?
