For me, I have experienced some Chucking when I forget to select the "Alternate Ride Height" on my Ram 3500 air suspension. It lowers the rear suspension a few inches and in that mode, I never feel any Chucking. By lowering the front ride height of the trailer, you're putting more pin weight on the hitch, which, in my case, makes a huge difference with my 36 foot Open Range Fifth Wheel.
