I was able to pry off the first section of floor decking and see how it was constructed. The whole underside of the travel trailer was wrapped in a type of weather proof fabric, hiding the beams and seams. Knowing how the flooring is constructed and installed is very helpful when you need to remove it. Tomorrow should be a productive day as well. I hope to remove all of the decking and also haul a bunch of trash to the curb for the trash man. I posted some pics below.
