Went in today to complain about the mirrors shaking with 1400 miles :uhoh2: , the tech. came out and talked to me. Will hears what he said was the cause, my LIFT KIT :wtf: . I said what lift kit as I now was going to make him more of an idiot :Get_him: , having to tell him do you how the stock 2500HD's ride? Like a pogo stick bouncing :bounce: around over every little bump unweighted with a long bed. In that mine, I said what I did improved & smoothed the ride out & wheres the LIFT KIT? For PR reasons we will change both, if this happens again I will have to talk to the service manger. Are the techs that dumb now a day :idiot: ?
