I have a Challenger 37KT and put front/rear sumo springs. It feels like a different coach. The sway is much better than the CHF. The first thing you will notice is going off a driveway and turning.
I notice less movement from lite winds and trucks as they pass by. Long drives seen much more enjoyable.
It also helps quite down the ride of a normal freeway as I hear less rattles. But a bad road or dirt, not much change.
The last improvement, although slight, is when parked and levelers down it feels a little more stable when walking around the coach.
Overall I love them and would repeat. But you need to do both front and rear. I have heard very similar results with others but not so much when they only did the front.
