Brian,
Before I got my Slide in Popup Truck Camper, I had a pop-up camper in Atlanta. It was the perfect setup. Lightweight, and very easy to tow around, hell I use to tow it behind my trailer it was so light. There are some things to look out for, if you are buying used, make sure you check the canvas for mold an mildue. Like was stated above, make sure you can access the camper with the door down, much easier to load and unload.
Don't buy new, they are way overpriced, there are lots on Ebay and used. You can get a hell of a deal buying one used, get one with all the stuff if possible. They get cold in the colder weather, some of the newer ones have AC, and heaters.
Once you move up from a tent, you got to a pop-up then to whatever, everyone who camps alot, at one time or another has used a popup.
Good luck and enjoy it, they are a lot of fun.
Rob
