M-915 Series Heavy Trucks
62nd Transportation Company M915 tractors in an Interstate rest area near Ft. Bliss, TX, 12 February 1987.
The M915 series of vehicles consists of six trucks that utilize the same power train, axles, and chassis with different body configurations. These trucks were produced starting in 1978, and, after a series of upgrades , continue to be utilized by the U.S. military forces in the 2000s. Plans for further life-extension through retrofitting and reinvestment in the fleet will push the M915-series useful life into the second or even third decade of the 21st century.
