Fuel Economy and Range

No MPG figure is published for the Silverado 2500HD. Trucks above this weight are exempt from federal fuel-economy labelling, so no configuration carries a city, highway or combined figure. Any MPG number attached to a 2500HD belongs to a different vehicle. What the manufacturer does publish is fuel tank capacity: 28 to 36 gallons by configuration, with 36.0 gallons on the Crew Cab.

What These Specifications Mean in Practice

Three numbers do most of the work. The 142.00-inch wheelbase and 235.59-inch length on a Regular Cab long bed tell you this truck needs a real parking space; a Crew Cab long bed needs more. The 81.75-inch width at the rear fenders excludes mirrors, which matters if you are measuring a garage door or a job-site gate. And payload falls as capability rises: the 3,926-pound figure belongs to the lightest configuration in the lineup, and every cab, drivetrain and engine upgrade takes some of it back.

For buyers in Hot Springs and across Garland County running out to Malvern and Arkadelphia, or to Bryant over in Saline County, the practical decision is usually bed length before trim. A Bryant driveway takes the standard bed more easily than the long one. The long bed is what unlocks the 22,050-pound gooseneck rating, and it is the harder thing to change later.
