The GMC Sierra 1500, capable as it is, may not be large or powerful enough for some folks looking for a new pickup truck in Houston. Some of those same people will find the GMC 3500 HD a bit too much truck. The 2020 GMC Sierra 2500 HD is a happy medium between the extremes, and it's available now at Gillman Chevrolet Buick GMC.

2020 GMC Sierra 2500 Details   

The 2020 GMC truck lineup is redesigned, leaving the Sierra 2500 larger and stronger than before, but offsetting this year's higher GVWR and GCWR with more power. The standard V8 gasoline engine is all new. The V8 Duramax diesel engine is a known quantity, but it's retuned slightly since it's paired to a new ten-speed Allison automatic gearbox.

Working out capacities and capabilities is something best discussed with your GMC dealership near Brownsville, TX, since this truck's towing capacity, payload, and other features depend on cab and box configurations, and whether you choose a standard, fifth wheel, or gooseneck hitch.

When properly equipped, however, the GMC Sierra 2500 offers a maximum towing capacity of 27,500 pounds and a maximum payload of 3,553 pounds with either the standard 4x2 or optional 4x4 driveline.


2020 GMC Sierra 2500 Safety and Special Features

That strength is matched by plenty of smarts. Safety features include class-exclusive features like a heads-up display and rear camera mirror, and a transparent trailer view that's the first in the industry. The latter feature offers one of fifteen different available camera views in the GMC 2500 by attaching a camera to your trailer for a panoramic view of the road behind you.

While the AT4 trim, with its off-road suspension, skid plates, Rancho shocks, and all-terrain tires, is great for off-roading, there's no disguising the fact that these are work trucks. Take a good look at the available MultiPro six-position tailgate. Also ask about the ProGrade Trailering System, which incorporates not only the aforementioned transparent trailer view, but also cameras for views of the sides, trailer, and hitch, an electric parking brake, and its own smartphone app that's mirrored in the infotainment display.
