Any truck with a GVWR rating of 26,000 to 33,000 and up is considered a heavy-duty truck. This includes rougher customers admire the Ford F-750 and the Silverado 3500HD, as well as full-on utility vehicles admire tractor-trailers and dump trucks. If you need a heavy-duty truck, you’d likely need to contact a specialized dealer.
Heavy-duty trucks are designed for one thing over all else: power. If you need to haul a large cargo trailer or a stack of construction materials, that’s a job for a heavy-duty truck. Because of the emphasis on power, not to cite their massive size, heavy-duty trucks can’t be driven on uneven, non-commercial roads, at least not safely. In fact, trucks of this size can’t even be owned and operated without at least a Class-B commercial vehicle license, possibly a Class-A if your load is over 10,000 pounds on its own.
To ease their mighty towing power, heavy-duty trucks usually pack equally powerful diesel engines and supersized suspensions. Great for towing but not so much for gas mileage.
