I would not consider using TB2 for waterproofing, only adhesion of the canvas to the foam.
The results after years of real-life usage will not be the same as a short term test.

Hmm. That reminds me of the time I used regular wood, instead of pressure treated wood, on a foundation of a small shed. I painted those foundation pieces but after 10 years of sitting on concrete, they still needed to be replaced. I can see that happening to any wood or canvas in a camper where it is in contact with the frame.
I do Not recommend pressure treated wood in a camper build. I'd be afraid of what it might "off gas" inside the camper, and there is a reason that's for exterior use only.
The drip edge idea is a good preventative idea, I'd like to see a picture of where you put that on the camper.
However, I'm thinking that we should come up with a way to protect bottom edges of canvas so that doesn't happen again. Anywhere that canvas makes contact with the frame, or floor, should be protected better.
Feel free to shoot this idea down and give alternate ideas. We should do some brainstorming here. My first thought is using epoxy to saturate the canvas fibers at the base. Then paint over that, just like the canvas. I've never worked with epoxy in this way so I'll leave that discussion to people that have.
