Well the Koni shocks are installed. I noticed a immediate difference in how the coach reacts. Bumps are much smoother and less of a bouncy feel. Not as much dipping when stopping. The biggest difference is side to side when turning much less body sway especially when transitioning from a driveway to the main road where the drive was higher. It stopped the floating mushy feeling when driving down the highway when there was a difference in the road terrain.
We had around 2600 miles on the original Sachs that came with the rig. I believe I'm not going to regret the decision to switch. Our MH is 42' and a single axle DP at about 28,000 lbs loaded (without toad).
