We have a 06 Grand Cherokee Laredo, 4.7L, 4WD with class 4 tow package. We are looking at getting a camper (4000-5000 lbs dry weight, 26-30 ft bumper-to-hitch). I've heard that a short tow vehicle wheelbase can cause sway for a longer trailer. I was looking for others experiences towing a camper, and how long of a trailer I could comfortably tow with the GC. We are planning to use an weight distribution hitch with swaybar. Anyone have any experience of what works/doesn't work?
