Ripon, CA | Honestly i would stay away from the MX. Im also MX certified. You need to do everything to the T on these for maintenance. Air system management cleaning periodically, using OEM filters, if your having a shop work on it they need to know what they are doing. You can only get parts for them from a peterbilt or KW dealer. 2017+ MX engines had camshaft issues there was a campaign to replace them but still have issues, CCV filter modules go out, liners dropping and causing headgaskets to blow (Cummins has this problem to), air compressors go out.(PIA to change) 2020+ have injector issues.
