Stay at a park a month or more then move on and do it again?

I’ve been doing that for years. I stay for anywhere from 1 to 3 months at a lot of State, County and Municipal parks along or near I-10 from late Fall to early Spring. Many are not very busy that time of year so they are happy to have any cash flow they can get to help pay their utility bills.

That said, don’t expect everything to be cheap or free. Rates can vary wildly. The RV lifestyle is expensive if you avoid the real dumps.
