Our 2019 Superduty F-250 6.7 is a beast to tow with but our 30 ft Airstream with 1100 lbs of hitch weight can get its attention on bouncy back roads fast!. I originally had only one spacer but am now installing the 2d one so I get more compression. While not perfect it does tame down the bouncing on non smooth roads. I also have the ft coil sump springs installed they took out the ft end dip and sway on corners. I feel no negative ride quality from installing these products.

Truck rear sumo springs is set for contact under load. Much improvement with towing. Sumo spring on travel trailer with continuous contact seems to have a smoother ride. I’m pleased.
