Set up an LLC in Wyoming and transfer the Motorhome into it. Get a driver's license and use that address. No personal property taxes, no income taxes. no vehicle inspections and you never have to spend a winter there.
I have friends who have done that. Small place in Wyoming + a motorhome and a small condo in Henderson, Nevada. When it gets cold in Wyoming, they are gone: either on the road or in Henderson for the winter.
