The only two issues I see are
1. RVing in January in Michigan is a challenge for an experienced Rver, and for the inexperienced approaches impossible. I would rethink that one. Possibly an extended stay facility and winterize and park the Rv is a better option.
2. I understood part of your exit plan includes selling the RV and truck if necessary and using that money to buy a modest house. RVs depreciate like a rock in water, and trucks not far behind. You may find yourself with just enough money to pay a deposit on an apartment!
