I’ve had my doetschs for about a year and a half now and haven’t had a problem with rust yet. Then again, they don’t salt the roads up here and I try to stay out of the creeks. You are right about them being soft; they feel kind of mushy to me. The best way I can describe it is like an old Cadillac, that sort of floating feeling. I prefer a stiffer (but not harsh) ride. I want to go with the Ranchos because of the 9 position adjustments. I figured that would give me some leeway to adjust the ride softer or stiffer as needed. That must be why they make so many different types of shocks, pick what ever suits you.
