My 2 cents..
I often (daily ?) wonder where I'll move when it becomes intolerable to live in Cal
Your timing's all wrong to be buying/driving a motorhome > 3 miles/gallon @ $ 3.30/gallon...
Plus, if you buy a new motorhome, the depreciation is a killer.
Alternate plan:
Pick area of country to live.
Sell Cal house
Relo there.
Periodically, load up the family sedan/van & take a trip
to a desired destination.
All of America is not worth seeing...but most is.
Plan carefully & don't bother w/ the rust belt, etc.
