About the 2015 Chevrolet Silverado 3500
3rd-generation Silverado HD (2015-2019), first model year and full redesign
Chevrolet positions the Silverado 3500HD as its maximum-duty pickup for moving large trailers and heavy payloads while still serving as an everyday work vehicle. Its identity centers on V8 power, an integrated towing system, a fully boxed frame and a durable steel cargo box. Multiple cab, bed, rear-wheel and drivetrain configurations let the model cover commercial work, equipment towing and large recreational trailers, while upper trims add passenger-car-style comfort and technology.
The Work Truck remains the straightforward commercial model, while LT adds everyday conveniences and LTZ brings leather seats, an 8-inch touchscreen and a rear camera. The new High Country sits at the top with heated and ventilated leather seats, Bose audio, parking sensors and a factory spray-in bedliner, combining long-distance comfort with the truck's heavy-duty role.

“I have been a GM (Chevrolet) customer for many years and have no reason or desire to change at this point.”
“Gas miles suck -- Looking at the Dodge 2500 next truck unless Chev does something about the gas miles. Towing a 5th wheel average 6 to 9 miles a gal. Around town own on a good day 16 miles per gal.”
