Now that all of the wall panels are removed, we can access the screws holding the subfloor to the frame. I left the panel in the back because the previous owners already replaced the subfloor in that corner AND that panel is massive. Lucky for me, the wall framing is in great shape! The bad news is the front panels were made of asbestos or some kind of brittle material… probably going to have to get more aluminum for that area. I had to remove the fiberglass covers for the wheel wells to get to the lower panels on either side and luckily they are also spray foam insulated! I am not sure what is under the subfloor in terms of insulation and I know that the belly pan has to be replaced in some places… overall not too many bad surprises, as long as the frame under the subfloor is in decent shape.
