I use a ProPride with my '17 Cummins and only occasionally get a little bump. I use the auto exhaust brake on mine when towing so the exhaust brake only engages if my speed goes above where it was when I let off the throttle (like downhill) or if I touch the brake pedal. If I forget to select auto and use full exhaust brake, I rarely get a bump upon letting off the throttle. I actually find I get more of the bump when I come to a complete stop. The brakes on my early '17 BHBE are Lippert's and are very weak. They have been pulled apart, cleaned and adjusted and still the truck idling will pull through the max trailer brake using the factory brake controller. If you have Dexter brakes you probably won't get much bump at all.
Either way, you won't regret buying and using the ProPride. Of course, you may never get into a sway condition with any other hitch. Problem is, you won't know until you are swaying! Even at $3 grand, the hitch is cheap. Truck is $60 - $85 grand and the trailer is easily $30 grand and up...
