# 2026 GMC Sierra 3500HD Crew Cab 4WD DRW Enclosed Service TruckEngineered to handle severe commercial job sites across the Dallas--Fort Worth metroplex and Weatherford, this heavy-duty work truck combines high-output diesel capability with full weather-protected mobile storage.### Heavy-Duty Powertrain and ChassisPower comes from a 6.6-liter Duramax Turbo-Diesel V8 delivering 470 horsepower and 975 pound-feet of torque. It pairs with an Allison 10-speed automatic transmission, an integrated engine exhaust brake, and an engine block heater.

Dual rear wheels provide stability under heavy payloads, supported by a 3.42 rear axle ratio, a 40-gallon fuel tank, a high-output 220-amp alternator, a factory 5-circuit upfitter switch kit, and a Class 5 rear receiver hitch.### Monroe Royal Enclosed Service UpfitThe rear workspace is built around a Monroe Royal 9-foot service body topped with a TSS-1-108-75 SuperStructure canopy.
