Hi, this is my first crack at this! I love this organization. It’s gotten me out of trouble on many occasions! MJ, sounds like you’re on top of things, while you’re checking for rust make sure you get on your back and crawl underneath check out the framework for the basement. Also run everything ( Air conditioners/heat pumps; generator; furnace; fridge/freezer; washer dryer; slides; awnings; battery compartment; water pumps; electronics etc. Take your time try everything!
