Great running lbz duramax, haven’t put a lot of miles on her. New 6” straight pipe exhaust, banks intake. Automatic side steps. New 35” tires. 5th wheel hitch and trailer brakes. Transynd transmission fluid change new exterior filters with the stuff for the next change. New rear differential oils changed, new oil every 3k or less because I change every 3 months regardless. Low miles come n get her.
