Back of the envelope calculation would be: side area of camper/truck about 20 x 10, center of effort about 6 feet high, dynamic pressure at 70 mph is about 12.5 psi, call the coefficient of drag 1, so you have 20 x 10 x 6 x 12.5 or 15,000 ft lbs overturning force. In my case, truck + camper are 13000+, track of dually at least 6.5', so to pick up one side would require 13,000 x 6.5 / 2 or 42,000 ft lbs. At 100 mph, dynamic pressure is twice as high and I'd be worried. Or turn into the wind.
On the jacks, the camper weighs a lot less than the truck + camper so it would go over in a lot less.
