The truck I learned to drive on was a B-73 Mack with a 262 Cummins and a Tri-Plex 5X3 transmission. It carried a 1600 gallon water tank and we contracted it out for dust control on big construction sites in California. When I moved up to a 10 speed Roadranger in a 64 freightliner cabover with a 318 Detroit, I didn't know how to act with only one shifter to play with!
