james j neiweem Posted January 10, 2014 Share Posted January 10, 2014 I believe St Johnsbury had a bunch of U models with Cummins 903's. Watkins had V-8"s in U models . Not sure if they were Cummins or Mack. Roadway of course had the V detroits.

kscarbel Posted January 10, 2014 Share Posted January 10, 2014 Columbia (Lexington), South Carolina-based Southeastern Freight Lines ran a huge fleet of Cummins-powered Mack U-models. Talk about a sharp looking fleet, still to this day. The way Southeastern cares about the appearance of their trucks is akin to a fleet in the northeast.http://hankstruckpictures.com/pix/trucks/donq/southeastern_mack_u.htmlhttp://hankstruckpictures.com/pix/trucks/donq/southeastern_mack_u_2.htmlhttp://www.hankstruckpictures.ca/pix/trucks/morton/2011/04-07/prints/mack/scan012.jpg 1 Quote Link to comment https://www.bigmacktrucks.com/topic/34179-mack-power-optional-vendor-engines/#findComment-225883 Share on other sites More sharing options...
