Why do you need air bags with this truck trailer combo? 65 pounds of air in the rear tires seems kind of light but I don't know what you have on the truck for tires.I tow a 30 foot toy hauler running about 11000 pounds with a 2015 Ram 2500 short box while using the Anderson hitch that uses chains instead of stabilizer bars and I don't get any wiggle. Why don't you air your truck tire up to max as well as trailer tires, keep your air bags flat and try to load the trailer with 60% of the weight in front of the axles. Bet if your hitch is set up right the trailer will tow fine.
