Well here goes, I can only tell you what my friends are saying about there M2. Service has been a problem. Simply items like oil changes and filter changes have caused them lost time and revenue. Sorry for this type of report, but anything unique in trucking that differs from the usual Cat, Cummins, etc. seems to throw everyone into a tizzy! It will get better, only because it can't get any worse! There is a reason you see Cat and Cummins equipped vehicles gobbled up first, there easy to get serviced! So be careful and research your favorite truck repair facilities to see if they want to tackle your unique combination.
