I love mobility and travel, for others not having a home base would be very difficult...but when you are staying in short term lodging, it's amazing how many expenses just drop off: no utilities, no furnishings, no repairs, no maintenance and once i found a way to get most of it paid for through points, basically it was like living for free....and when I visited friends and family and stayed with them....it was completely free - but I often treated them to restaurant meals in exchange for hosting me.
My biggest expenses at that time were car insurance, health insurance (through my employer, so quite a bit subsidized) storage unit rental, and then gas and money for fun.
I have thought about writing a guidebook....it seems like a niche lifestyle not common....unlike van life or the like.
One lingering benefit is that after I moved into my new permanent home, I still had hotel status and points, so that has funded all my vacation lodging since 2022 and will enable a huge month long trip this spring.
It's not all roses though, so the other side is constantly moving, packing, unpacking and some AirBnB locations that turned out to be problematic....as time went on, I found myself staying longer and longer at each place - that was my cue to get off the road.
Life was passing like a hand waving from a train I wanted to be on
