I have torn out most of the interior including the dinette and sofa. I have also torn out most of the interior panels and most of the cabinets. Five rear and two front trusses are toast. There is rot around the top of the slide out and the slide out itself will need to be completely rebuilt. The roof membrane and plywood will also need replacing. I have taken out all of the carpet and vinyl flooring. There are no current mold issues inside.
The bathroom and kitchen area is in very good condition with no signs of rot. The entire floor is good to go throughout the unit. I will be able to rebuild this unit and make it nice again. I'm relieved that I don't have to demo the bathroom or kitchen.
Here are a couple of images I took during the demo.
