My family is renting an RV for 25 days in June. We have never used an RV and I have some concerns. Is it doable to stay at a state park (no hook ups) for 2-3 days then stay at a park with full hook ups for 1 day? (Then keep alternating it this way.) There will be 4 of us & I realize that the more water/sewage we use the sooner we will need to use a dump station. I also know that some of the state parks have dump stations even if they don't have hook ups. Can we refill our water supply at those places too? How many hours should I expect to use the generator when we don't have hook ups?
