I carry an Ozark-Trail-6-Person-Instant-Dome-Tent. When I get to my camping spot, I can set the tent up next to the van to keep anyone else from parking right next to me. I don't sleep in it, although I could. The van is just so compfy. I set up a table next to it, and some lawn chairs, and play guitar. I can put my junk in the tent, and if I want to go somewhere, the tent helps keep my camping spot for me. The tent makes shade for me to sit in, or I can actually sit in the tent.
But, I may need to get a small, beach type tent. Some festivals I go to are "walk-in", you park in the parking lot and carry all your junk in. No golf carts, so these type festivals have a much younger crowd. I figure I can walk in with a little beach tent, the kind you just throw and it's set up, a lawn chair, a small cooler, and a bag of toys (harmonicas, ukulele, etc). I won't sleep there like everyone else, I'll just have my spot claimed. I can sit there, drink beer, get out of the sun, then walk back to the van to sleep, get more beer, etc.
