We too are starting a year long RV adventure without a permanent residence. Only issue I've identified so far is the insurances. As others have said, everything is on line with electronic billing and statements. Auto insurance seems to want a residence address as that's how they price out coverage. But the bigger issue for us is medical ins. We're not medicare age so have to buy on the open market. and at least with the blue cross plans, they're all regional and you have to access routine care in your "home" region. Not very helpful if your homie is on wheels.
