Seward Motor Freight was founded in the 1940s as less than a truck load (LTL) operations hauling freight from its hometown of Seward to Omaha, Nebraska and back. Willard and Wanda Miers operated Seward Motor Freight for 20 years before selling to Wayne and Joan Tanderup in 1969.

Today, the company operates class 8 tractors with 53’ dry box vans trailers providing service to all 48 contiguous states. The three main categories of trucks are light-duty, medium-duty, and heavy-duty, which are further divided into classes. Classes are calculated according to the gross vehicle weight rating – the total allowed weight of the vehicle.

Light-duty trucks occupy classes 1 through 3. These are the lightest and smallest trucks on the road. Class-1 trucks can weigh up to 6,000 pounds, while class-2 models can weigh between 6,001 and 10,000 pounds. Class 3 vehicles have a 14,000-pound limit.

Class 4 is the smallest in the medium-duty category, with a limit of 16,000 pounds. Class-5 models can weigh up to 19,500 pounds when fully loaded, while class-6 models can weigh up to 26,000 pounds.

Heavy-duty trucks start with class 7, which have a 33,000-pound limit. Class 8 starts at 33,001 pounds. Class 9 can weigh up to 80,000 pounds but may need special permits.
