Navajo Shippers hopes you'll say h�g�onee' (the Navajo word for goodbye) to other refrigerated trucking companies. Through its Navajo Express unit, Navajo Shippers provides temperature-controlled freight transportation, mainly in the western US. It operates a fleet of about 900 tractors and 1,750 trailers from terminals in Arizona, California, Colorado, Tennessee, and Washington state, and it offers service elsewhere in the 48 contiguous states via partnerships with other carriers. Navajo Shippers also provides logistics services. The company, which has grown over the years through acquisitions, is owned and run by President Don Digby Sr. and his family.
