Digby Truck Line and Navajo Express are both owned and operated by the Digby family of La Vergne, Tennessee (although Navajo is headquartered in Commerce City, Colorado.) Digby handles the dry box and flat bed cargo and Navajo specializes in temperature controlled cargo. It is common for Navajo tractors to pull Digby trailers and vice-versa as need dictates and that is what we are presenting here. Digby is one of the old guard of American trucking having been established in 1933! Conversely, their fleet is one of the newest on the highway. The trailer in this set is a Micro-Trains Line 48' Fruehauf painted and printed by deLuxe.
