Welcome to the forums and hope you have a great time with your new camper.
We also rented a pop-up from AAFES (If that's still the name of it today), when I was in the Army, stationed at Fort Belvoir, Virginia. We towed that little pop-up from Washington DC area to Norfolk, VA and stayed at (then) Fort Story, which today is First Landing State Park. We went from there, straight West and drove the Appalachia Trail route Northward, and then straight back to Washington DC. It was a fantastic trip and still have great memories.
Funny story if I may relay. We were at Fort Story, it was dark, a few other folks camping there, but really, really dark. We had a cat with us who figured out how to crawl out of the camper by climbing under the canvas wall where it snapped to the body of the box. When I realized the cat was out, I jumped out of bed and started softly yelling, "Here kitty, kitty, kitty", hoping to NOT wake up neighboring campers. My wife was inside laughing as I could hear here, even some distance from the camper. Believe it or not, I found the cat and retrieved it. Once back at the camper and the cat was safe again, I asked her why she was laughing so much. She said, ..... do you even realize you were running around that entire time with nothing on but your underware! ... um .. I knew I was barefoot, but didn't think about anything else! .... Nope!
