We haul very close to our max GVWR on a daily basis seeing 5 to 8 dealers a day so the truck experiences a work load on a daily basis. Before the Kelderman suspension was added you could feel so much of the road. After we added the Kelderman it feels as if we are on a cloud. It was amazing to me that while we felt like we were on a cloud, the truck, for its weight, handles great!! Great job Kelderman!! This type of workmanship is why we are coming back to put your kit on our 44’ New Horizon Toy Hauler.
