Test drove 2014 cc 8 spd 3.90 axle and 5-7 box with tractor and equipment trailer I use on 3/4 ton truck. Actual tow weight 7200 lbs. I had enough tongue weight not to have trailer sway on 3/4 ton truck. Hooked up to Ram without moving tractor on the trailer. Was not using weight distribution hitch on either vechicle. I have a lot of towing experience. Salesman attributed it to air ride being on. Any thoughts? I think its something simple not the fact it is a 1/2 ton truck.
