New Mack trucks are delivered in style with, in this case, four Granite units hooked together. Despite the Missouri plates, Macks are built in Macungie, Pennsylvania. The window stickers indicate a manufacture date of June 24 and a delivery date of July 19. This photo was taken at the Irving Big Stop in Aulac, NB on July 11, so they should make it in time.
By the look of the beefy front bumpers, to protect the Power Take Offs, these trucks will be used for transit mixers.
