It might be best to break the tasks down into three groups:
1 - Make it safe.
2 - Make it comfortable.
3 - Make it yours (meaning the custom touches that you want but don't really need).
You can further break down #1 into:
1A - Make it safe to tow.
1B - Make it safe to live in.
So, I have to agree with Stefrobrts, axles, brakes, tires, and hitch have to come first. Then propane system, electrical system, hygiene (mold/mildew), wastewater, freshwater, furnishings, and finally finishes, more or less in that order. Though you might decide on electrical before propane, or whatever, as best suits what needs fixing.
