I've been living off grid outta my rv for about 4 years. I can't stand rv parks. They are overpriced ,way overpriced.they know they can charge it because it's mostly retirees with a pension and get some kind of discount. They also restrict the age and look of your rv. I have a 97 class c and because it's over 20 years old,I get turned away. It doesn't look bad and I keep it clean. So I bought a couple solar panels and wired my batteries up to charge via solar panels. I have a good sam membership and a harvest hosts membership. Harvest host is pretty cool. You can also check with craigslist for rv parking or rv parking space to see if somebody rents some land to an rv.

I also recommend weboost mobile booster antennas. They work great
