Over the past four to five years, a lot has been written about the shift away from big-bore 15-liter engines to medium-bore (11-liter to 13-liter) engines. This was particularly true among truckers looking to minimize fuel costs.
New data shows that many of the industry's trend-setters have discovered the truth in the old saying, "there's no replacement for displacement." They've come to understand the benefits of new technology in the big-bore engines, and have been making the switch because it saves them money. The comeback has been dramatic.
Wendy Parker rides with her husband, owner-operator George Parker. After years leased to carriers, the couple's business today runs under its own authority during the show season dedicated to the Diesel Life touring operation, booking loads on the spot market via TruckItSmart's load board in the off-season. She chronicles their adventures and her observations from the shotgun position in her blog, originally launched at the couple's George & Wendy Show website.
