Yeah - after seeing this thread title the other day, the first truck I saw was a Mack dirt hauler.
What made me post, tho, was the fact that Townes Van Zandt’s White Freightliner Blues has been my current earworm lately! Hopeing to infect some of youse guys!
Yep. We call them tandems. As in two rear axles. “I need a tandem load of gravel” About 8-10 yards, depending on the work site and what pass it has to be hauled over.
