I’m new to this forum. Just registered. I’m 70, Widower so it’s just me and the dog. I’m contemplating that by age 75 +/- to sell my house (I own it outright) purchase a class C, 24-26ft and live life on the road. What I don’t know is how much annual $$ can I expect that kind of life to cost me. Camping fees, fuel, etc. what I also don’t know is how would I establish an address for mail and all other communications besides phone. How do I establish state a residency? Input appreciated.
