The 2019 Chevrolet Silverado 3500HD High Country dually is a well-mannered, refined machine with a maximum fifth-wheel towing capacity of 22,700 pounds. 

It’s a requirement. If you’re going to haul a supersize fifth-wheel or truck camper, you’re going to need a heavy-duty truck. And, if you’re spending a lot of time on the road, you’ll want to be comfortable.

GM has injected some Cadillac-like features into its trucks for years, and if that kind of style is what you’re longing for, and you have the pocketbook, then the 2019 Chevrolet Silverado 3500HD High Country dually will grab your attention. The High Country package packs just about as much plush and tech into a truck as possible. Supple-leather front 12-way power seats with heated surfaces and air conditioning are embroidered with the High Country logo on the back, while the rear seating is similarly comfortable and roomy. Back-seat passengers will be kept to their own devices with the optional rear entertainment system integrated into the front seat backs ($1,620).

In the cockpit, the Chevrolet MyLink Infotainment System, with an 8-inch touchscreen, provides access to all the integrated features, including Apple CarPlay and onboard navigation. The tunes, provided by every source imaginable, including SiriusXM, are belted out via the Bose seven-speaker sound system with subwoofer. Most of this can be controlled using the buttons in the heated leather steering wheel.

The jet-black interior complements the Cajun Red Tintcoat ($495) single-tone exterior with chrome accents and 17-inch polished aluminum wheels. A spray-in bedliner is standard, and a fifth-wheel prep package ($370) makes installing a puck-mount hitch a breeze.

The Duramax Plus Package ($9,645) includes the 6.6-liter Duramax eight-cylinder turbo diesel, six-speed Allison transmission, 3.73:1 axle ratio, exhaust brake, chrome recovery hooks and more.

In comparison to the competition, the Chevy’s towing capability is at the back of the pack, with a maximum fifth-wheel-towing capacity of 22,700 pounds for the 4×4, and 23,100 for the two-wheel-drive model. This is adequate for the majority of RVers, however, and given the proper manners this truck exudes, the lower rating is a minor compromise for most.

The 3500 High Country diesel is remarkably quiet and handles competently, whether loaded by the test Cyclone on the interstate or running empty around town. The dual-wheel skirts gracefully extend from the molded bedside panel but, like most duallies, can impact parking in narrow spaces in shopping areas. Then add the Crew Cab, and you’re walking a mile from the outer parking lot.

While this truck does a good job towing larger trailers, GM announced at press time that an all-new-from-the-ground-up 2020 Silverado HD will be released. This new truck moves Chevy to the lead spot in towing capacity at an astounding 35,500 pounds, which 99 percent of all RVers will never test — a 52 percent increase over the 2019 Silverado HD. The completely redesigned chassis features the new 6.6-liter Duramax diesel and a 10-speed Allison transmission. The truck, via the myChevrolet mobile app, will integrate with the iN-Command system in many Keystone trailers, allowing control of numerous trailer features right from the truck’s radio head.Red 1029 Chevy Silverado 3500HD High Country towing a fifth wheel trailer on an Indiana road.

  1. My concern is about the RV external drain hoses. Why do you or the manufacturer never tell us, the buying public, what the mil spec of those hoses are? That plays a very important part when it comes to a various temperature range and durability.
