I wonder if there's a different shock type that should be used on an RV that is further away from it's chassis weight maximum versus an RV that loads it's chassis close to it's design weight maximum?
Our 24 foot Class C definitely underloads it's E450 chassis, so it's ride in the rear was very stiff with OEM shocks. I retrofitted the rear OEM shocks with Koni FSD shocks back there and the sharp pounding in the rear on highway cracks and potholes has definitely been improved.
Yet other Class C owners in these forums who have tried Koni FSD shocks report not being especially impressed (note that "Koni FSD" shocks are NOT the same as other Koni shock types) . Is the difference in FSD impressions due to a light Class C versus a heavy Class C?
I'm still scratching my head over what shocks to use in the front to replace the OEM shocks. At ~76K miles on our rig, maybe it's time - but our mechanic still says not yet on the front shocks. Why are my front OEM shocks (and the OEM front steering damper) not worn out yet?
