? much help will 3/4 ton make for ride quality comp to 1/2?

I tow a 23 ft 6000 lb. loaded TT with a Chevy C3500 dually and still can fill the push pull of a big rig passing. I think its just the nature of the beast. I don't notice it as much as I did with the Dodge 1500, but its still there. I have just learned that when something big is going to pass to hold on the let off the gas a little. It helps a little bit.
