Thanks everyone for the replies. I am in the Air Force and will be stationed at Ft Bragg. I checked into the Fam Camp previously but they only allow you to stay for up to 90 days at a time. My wife and I found Heritage RV Park in the area that we originally wanted to live in, so we have a reservation there. It's tucked out in the woods with a lake and you can stay as long as you like. Originally my goal was to try this out for 6 months and then if we liked it we would move into a bigger camper or possibly a motorhome. I've wanted to do this for a while and luckily we are both very active and love the outdoors and exploring as well as we don't need much stuff.
I will definitely look into the famcamp at Camp Lejune as well. Sounds like a pretty nice spot to visit.
