I tow a 28' enclosed car hauler with a Dodge 1500. The empty weight on the trailer is 4500 pounds. I carry about 2000-3000 pounds of cargo. I have a WD hitch and airbags on stock suspension. The rig rides great, pretty much no issues at all. I think it has a lot to do with the way the trailer is loaded. The trailer is designed to carry one car toward the rear with the engine just foward of the rear axle. They are not made to have a lot of weight up front or on the back end, it's a balancing act. I don't haul a vehicle so I spread the weight out putting the heavy stuff just foward and on top of axles, lightest stuff up front and on rear. I think if you load differently it will help you, if that's even possible with tractors. If one is heavier put the front end just a little foward of the axles. Also be sure to check air pressure on all tires. Make sure they are inflated properly.
