They are having good sales here in Puerto Rico. So far the new ones have been cleared-out of the bugs that plague the first generation MACK MP-SERIES, camshaft and inyector issues are gone. One mayor fleet operator has 6 MACK PINNACLE Rawhide and drivers seem to like it so far so good. I am a little biased towards MACK but I know the had some issues with their EPA engines for the ASET series and first generation MP-SERIES (2004-2007). MP-8 505 HP gets the job done, you don't need 600+ HP for some situations and specific loads.
I do wish to test drive one with the M-DRIVE automated manual. But for now the MACK PINNACLE RAWHIDE EDITION is way better than ProStar or Cascadia in both, styling and performance.
