Which hitch setup will work the best?

I wonder what the delivery driver drives and what hitch he uses for these heavyweights?

Most of them drive 1 tons or larger with a really heavy hitch setup. Some have the suspension upgraded for towing. Some carry or use a WDH or a sway control built for the truck.

I find it strange that your front end does not change height. I have 4 WD with the towing and plow packages, and my front end will raise with 5K lbs on the hitch. Have you measured the fender height with and without load on he hitch?
