I've had the Racncho RS9000X on for a few years ( 90% hiway use ) with the 9 way adjustments, all 4 shocks at my door for around $200 ( BUY 3 GET 1 FREE W/FREE SHIPPING ) it had the option for the inside cabin control unit which I passed knowing there would be problems in time. I set mine on 6-7 and love them...
