About the Peterbilt 337
Introduced in 2010 with both PX-7 and bigger PX-9 power, the 337 was rated up to 33,000 lb and built as a straight truck or tractor for wreckers, tankers, and utilities.
About the Freightliner M2 106
Introduced in early 2002 out of a $250 million development program, the M2 106 anchored Freightliner's new Business Class M2 line and replaced the older FL-Series medium-duty trucks. Its name comes from its 106-inch BBC (bumper-to-back-of-cab) dimension, and it launched with the Mercedes-Benz MBE900 as standard power, growing into one of the most common Class 6-8 work trucks on US roads with GVWRs up to 66,000 lb.
