Teardrops n Tiny Travel Trailers

So we have built an almost waterproof and very rugged trailer, so of course I had to begin cutting out floor sections. Here is a sample of the floor, cut out for the ventilation and AC ducting. That is 2" solid and the lamination is amazing. The top canvas in the photo is actually the bottom layer. I was able to pull/tear some of the canvas from the ply, but it wasn't easy. None of the other layers will budge.
