Stopping Overnight

I stay in rest areas and truck stops all the time. I am as entitled to stay there as much as the truck. I would think they would want a truck stop more then a rest area though. Why is simple, I will pull in about 9 am and will pull out at 4 am. I have a resonator and my DP is a bit louder then most as a result. It is not super load but if you were in a tent it is louder then the dodge pickup. THen there is the issue that campgrounds are not always open especially in the north during the winter and some close in Oct and I go year round. There is no other option then. Finally, I started out on a trip on the saturday of memorial day weekend. Do you think there is a campground avail. NOT. Same thing this weekend. I doubt if you were traveling cross country you could find a place on the 4th of July weekend.
