What do ya'll know about the M2? Engine options, issues, power etc? Is it just the Mercedes or is CAT available? I know nothing on the Mercedes. Shop I usually go to isn't a fan of Freightliner period but I'm exploring my options before buying a new truck. The International 4300 was a good truck and a good engine but just lacked the power. I know of higher HP models but appears that they only turned up the boost in regards to keeping with the DT466. I know there is a 530 avaiable but know nothing about it either.
