I'm going camping this weekend and will by using my 2006 Pathy as a "tent." With all of the seats down, it easily holds a twin size infatable mattress so it will be perfect. Thing is, I will be camping in Florida where it's quite hot and there are lots of mosquitoes, so I don't want to leave the windows down. I think I'm going to let the car idle all night so that I can use the A/C. Anyone ever done this? How much gas do you think I'll use over 8 hours of idling?
