Once upon a time, before being homeless was popular, my kids and I lived in a travel trailer, and we pulled it with a super banana yellow dodge tradesman van. We never really left CA, except once to go to AZ for the weekend with some friends. It wasn't a bad life, but that was LONG before I started mystery shopping, my youngest son was still an infant, and the older boys had just started elementary school. I hadn't even learned how to be a mechanic back then, I had to pay someone to put freeze plugs in my van..
I don't think I could do that again without having a home base, and I know for a fact that a van wouldn't cut it. It would have to be at least a small class C motorhome. But I can envision going to see the glaciers in Canada like I we did when we went on vacation with my dad as kids. And going to see all the National Parks, might take more than one year though, because I'm not driving in the snow.
I could probably pull that off with just grocery shops and Image audits and my SS retirement.. though I'm probably not going to try. I may not like AL, but it's home and I chose this life.
