The Crew Cab version is perfect for going on an extended camping trip with friends or family. Blessed with great interiors (finally!!) the GMC Sierra is a serious beast. The 6L V8 is what powers this inhuman abomination of a monster we call a pickup truck. With its twin running in the race for the ultimate pickup truck, the General Motors show no mercy with both of them going head to head.

The bang-for-the-buck trim is the SLE, you get excellent features in your pickup truck for a reasonable price. The seats come with premium feeling leather and the infotainment gets an upgrade to a 8-inch touchscreen. GMC also doesn’t skip out on safety features, so you get a much needed rearview camera, to help you park this mammoth.
2020 GMC Sierra 3500HD Engine and Performance
“Although it's not as high-tech as the Ford Super Duty trucks, the slick GMC works just as hard.”- Car and Driver
The GMC Sierra shares its engine line up with the Chevy Silverado thus resulting in the same specs. These hauling brothers comprise of the lower spectrum of this category with Dodge Ram and the Ford taking the lead by quite a margin.

Amassing a difference of 20 and 50 lb-ft. the dodge and the Ford outclass the General Motors twins. But wait the highest trim of the twins offer a 6.6L V8 variant which generates a groundbreaking 910 lb-ft. This feat is not even challenged by any of its brethren.
Acceleration
The 6L V8 manages to race this monster on wheels to 0-60 mph in 6.7s. In real-world settings, we would usually not be bothered by the acceleration times of a pickup truck but 4 trucks racing down the streets is not a sight you see every day unless you are in the countryside. But if you do you’d know which truck to place your bet on.

The Ram achieves 60mph in 6.3 seconds. The Ford, despite the most endowed engine, reaches there 2 seconds slower than the Ram. The twin (Chevrolet)is as expected the same as the GMC
Ride and Handling
The three-tonne beast's driving serves as an antithesis to its uber powerful and intimidating aura. Surprisingly smooth and laden with a great suspension small potholes and imperfections fail to even make a mark on this high seater. Comfortably high over normal standards the stance is reassuring and provides a good view of the path ahead.
The huge size comes with its own fallacies and it shows when you park it in tight parking park or try to cruise it in traffic. The beast is a little hard to control at higher speeds due to the large momentum that builds up. The engine revving can’t be heard due to the excellent cabin noise isolation.
Braking
The auto grade braking fails to put a stop to the momentum built up by this truck and manages to stop it in 210 ft whilst decelerating from 70 mph. Faring on the worse side of things this GMC Sierra for some reason is worse off in this department as compared to its General Motor twin the Chevrolet Silverado 3500HD

The Dodge and the Ford take the lead in this parameter and come to halt in a 202 ft, considering the fact that the weight of all the trucks is in the same bracket it is safe to say who takes the pole position in this test.
Towing Capacity
A monumental towing capability of 13000 lbs. only lands the Sierra in the middle of the table and the Chevy follows suit.

The Dodge Ram takes the cake for lugging the most amount of weight and is the most utilitarian of the four trucks while the Ford offers the least hauling capacity.

EPA does not rate trucks, but due to the nature of these lugging monsters one should not expect very good numbers.
2020 GMC Sierra 3500HD Interior
8.0/10
“The Sierra HD has a spacious front seat and its cabin is extremely well designed. However, the top-of-the-line Denali fails to deliver the premium feel we would expect given its premium price, and the crew cab's rear-seat passenger space takes a back seat to the Ford pickups.”- Car and Driver
Seating and Comfort
The brash and abrasive looks might lead to a preconceived notion of a barebone interior but to everyone’s surprise, it's as luxury-laden as the price point and class allows it to be. 12-way adjustable seats and a spacious, roomy cabin all leads to a grander than expected cabin. The only thing that might irk a few people is the offset steering .

With the Chevy and the Dodge capable of hauling more weight than the Sierra as a choice for lugging seems redundant and almost uninformed.
2020 GMC Sierra 3500HD Safety
7.0/10
The GMC is certainly a very capable truck, which is why GMC has added a long list of safety features for passenger safety as well as driver-assist features for trailering as well as graded climbing and descending. The truck isn’t rated for passenger safety through crash testing by NHTSA or the IIHS. The features are listed as follows:
Frontal driver and right front-passenger single-stage airbags
Rear Vision camera system
StabiliTrak stability control system
Rollover mitigation technology
Trailer sway control
Hill start assist
Lane Departure Warning
Forward Collision Alert
Safety Alert Seat
Front and Rear Park Assist

2020 Chevrolet Silverado 3500 HD
Better payload capacity but less posh interiors. The twins offer the best of the best in this category and it boils down to personal preference at this point. With the same engine, transmission and equipment it what you need the truck for that drives your choice
2020 Dodge Ram 3500
Dependable and sturdy the clunky gearbox is what lets the loyal customer base down, couple that with an underpowered engine and you’ll definitely feel that there are better trucks out there. Tacky interiors are the downfall but which is made up by the class-leading hauling.
2020 Ford F-350
A redesigned truck endowed with a lot more features than its previous generations, it fails to drop the affordable tag. Although loaded with better safety and driver assist features it is a better deal than the General Motors twin. The top trim also offers better torque as compared to its brethren.
2020 GMC Sierra 3500HD Final Verdict
8.2/10
In an oversaturated market creating an image and demand for oneself is tough. But this uphill task is done splendidly by GMC and Sierra is a worthy competitor to the throne. The twin Chevy Silverado win in the towing and payload departments but the GMC takes the cake on the interiors.
