Which Sierra 3500HD does Edmunds recommend?
If you're looking for a capable heavy-duty truck with an impressive amount of equipment, we recommend the midlevel Sierra SLT. It has a wide range of available option packages along with lots of standard gear such as leather upholstery, heated front seats and power-adjustable seats. And if you want Denali-level creature comforts, you can get most of those as packaged or stand-alone options. For towing heavy trailers, we'd advise getting the 6.6-liter diesel V8.
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, redesigned 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. Next year's Sierra HD should do better.
Using the Sierra's infotainment 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.

SLT 4dr Crew Cab SB (6.0L 8cyl 6A)
Put about 1000 miles on mine, and so far, the whole family is impressed. Mileage has been great and I am shocked at how quiet the cabin is. So far, I must say, I’m a bit spoiled now.
