Can you TENT camp at CARLISLE

We are going to Carlisle and wandering if you can tent Camp there. Since my wife isn't going I don't have to get a hotel with a spa and my son wants to "Ruff It". I want to show the car but wander if I got Vendor spot and just stayed there. Can you spend the night there.
If you get a spot make it out in the area closer to the main gate. If back by the turnpike the truckers keep you awake all night- seems to be a game blowing their air horns as they go by- as if the truck weren't noisy enough....
