What Is Medium Duty? A Truck Class Guide for OKC Fleets

What is medium duty, exactly? It is one of the most common questions we hear from OKC business owners shopping for their first work truck, and the answer comes down to weight, not size or looks. Trucks are sorted into classes by gross vehicle weight rating, and medium-duty trucks sit in the middle of that scale, above everyday pickups but below the biggest rigs. Knowing where a truck lands helps you match it to the job, the licensing, and the budget. In this guide, we break down the classes, where medium-duty falls, and which Ford trucks fit. Have a job in mind already? Bob Moore Ford Pro can point you to the right class today!

What Is Medium Duty? 

Every commercial truck in the country is grouped into eight classes by gross vehicle weight rating, or GVWR, the maximum loaded weight a truck is built to carry. Light-duty trucks, including most pickups, fall into Classes 1 through 3. Medium duty trucks occupy the middle of the scale, and the heaviest highway rigs sit at the top in Class 8. The system matters because GVWR affects licensing, registration, and what a truck can legally haul. Our team can also line up Ford Pro financing once you know the class you need.

Where Medium Duty Falls

Medium-duty covers Classes 4 through 6, which run from 14,001 to 26,000 pounds GVWR. Class 4 spans 14,001 to 16,000 pounds, Class 5 runs 16,001 to 19,500, and Class 6 reaches up to 26,000. Some fleets also include Class 7 vehicles, up to 33,000 pounds, in the conversation. So what is a medium-duty truck in practice? Think box trucks, larger delivery vehicles, dump trucks, and bucket trucks, the vehicles that are too big for a pickup but not over-the-road semis. That is the core difference between medium-duty and heavy-duty: heavy-duty means they are built for the heaviest, often long-haul loads.

Which Ford Trucks Are Medium Duty

So what kinds of trucks are medium-duty trucks at Bob Moore Ford? For Oklahoma business owners, the medium-duty lineup centers on two trucks: the F-650 and the F-750. Both are built for serious commercial work, from stake beds and dump bodies to tow trucks and box vans. They slot above the Super Duty pickups and chassis cabs, giving OKC fleets a true medium-duty option without stepping up to a full heavy-duty rig.? The F-650 and F-750 are configured to your body and your workload. Explore build options through our commercial inventory.
