I pulled a 3200# camper with my 21 Tacoma for a couple of years. It did okay but I wouldn't go any higher. 3200 is not counting gear in the truck and people.
I pulled one of those little 13 ft fiberglass campers all over the place. If i remember right it had the dry weight of 1200 lbs and the car was rated for 2500.
Heavy duty leaf springs and air bags can do wonders. But if can swing a f250 you can pull that thing and it won't even squat the truck any. And you won't be blown around by the semi trucks. Or a smaller lighter camper.
