Which Sierra 3500HD does Edmunds recommend?
The SLT splits the difference between the two more work-focused lower trims and the decadent Denali trim. It offers leather upholstery, power-adjustable pedals, and an assortment of standard and optional features and packages, such as specialized suspension components. And when equipped with the optional 6.6-liter turbodiesel V8 engine, there's not much the Sierra 3500HD can't tow.
Edmunds' Expert Review
The optional 6.6-liter turbodiesel is an impressive engine that gives the 3500HD big towing numbers and impressive acceleration. Steering and braking are less impressive, but objectively this truck performs well by most standards that matter to truck buyers.
Overall comfort isn't the Sierra 3500's strong suit. Trucks in this size range aren't exactly bastions of comfort, but this one is particularly rough on the senses with a combo of stiff seats, lots of wind noise and a rigid suspension. A big payload, however, settles things down a lot.
The interior is likable and user-friendly. Hop in and you'll operate almost all the controls without busting out the manual. It has a no-nonsense vibe, but that's not necessarily a bad thing in this segment.
By most standards, the 3500HD certainly is utilitarian. It can tow and haul massive loads, and it has abundant interior storage. However, offerings from Ford and Ram outclass it by pretty much every measurement and in the arms race that is towing capacity, it falls behind by a few tons.
Using the MyLink interface is pretty simple, but we had several usability issues with our test vehicle. The finicky voice controls and subpar device integration made for a frustrating user experience.
