Just your car if you tow. No big deal if your not going far. We own one and take short 4 day trips. No big issue.
It’s not like one takes a 3000 mile trip. Some Retires take small trips to nearby states or to the ocean. We prefer an RV to a hotel room especially with Covid at least your in your own home.
And many families are buying in to live full time. Some people get a piece of land in a war state and park the RV there. Cheap living.
War state??
I can see why that would be cheap living.
