Cliff Viessman, Inc. has been involved in the reefer industry for many years. This was the first venture outside the realm of milk route trucks. CVI has two terminals dedicated to temp-controlled freight. They are Dawson, MN and Paynesville, MN. Dairy products are the major commodities hauled out of these two terminals with general freight being hauled back into the area. Our primary service area includes the Central and Midwest portions of the country.
