The wall was soft and would give when pressed. I also noticed that the screws that held the trim between the ceiling panels were rusty. I cut a small hole and looked in and saw it was bad the more I cut the worse it was. The wood frame was rotted all the way from the front of the door to the top about 2 feet wide. the wood crumbled like Styrofoam. It was all because the drilled a hole to mount the box awning and were off so the redrilled it about a 1/4 of the diameter. Once it got wet it just acted like a sponge and sucked in more water.
