Road trip tent camping anyone?

We just bought another tent to go camping at a camp ground down in San Clemente. Grounds are right up the bluff from the ocean and there is a liquor store on the other side of the street, a 10 minute walk :rolleyes:. Wifes friend has a kid our boys age so he'll be entertained. We got stow and go seating in the Caravan, I was thinking just stow the seats and hunker down in there? Sealed against the weather, warm...FLAT! No critters (none there anyway) Its like a double bed back there. Our Church youth group stopped at a rest stop on the way back from a 5 day hike in Utah. All us being about 13-16 years old, the girls got to crash in the RV while the boys got booted out to the cement slab next to the RV. I think it was early April and still butt cold. All night the rigs were on their jake brakes going down this grade, and I finally found that if I got ot one side and rolled myself up onto the folded portion of the bag, I could actually not feel the permafrost of the cement slab. That was a long night. I could really go for a trailer this time.....even a Coleman pop up.
