October was another strong month for U.S. medium- and heavy-duty trucks as sales rose 13.2% over year-ago, the best month since March 2007, due to solid performances in weight classes 4 through 8.

Led by Volvo’s Mack brand, which enjoyed a 23.6% increase, Class 8 was up 11.3% year-over-year on sales of 17,985 units as all players posted solid gains.

PACCAR’s Peterbilt saw sales rise 21.3% and International, which normally enjoys a strong October due to its fiscal year-end, was up 10.3%.

Class 8 volume leader Daimler saw its Freightliner and Western Star brands up a modest 7.5% and 4.3%, respectively.

October Class 6 deliveries were almost flat over last year, up a meager 1.2%. Second-place Ford, up a whopping 267.7%, closed the gap on class leader Freightliner, which saw sales slip 19.0%.
