2021 GMC Sierra 2500 AT4 Crew Cab w/ 4WD Review- Ridiculous

The 2021 #GMC Sierra 2500 AT4 is a ridiculously huge truck. And when optioned with the $10k #Duramax 6.6L turbo diesel engine, it doesn’t come cheap, either. But it does produce 910 lb.ft. of torque, allowing this beast to tow just about anything you have in mind. Plus, if you have a 5th wheel trailer it can handle that, too! M.S.R.P. – $78,050

Check out AutoAcademics’ full review of the 2021 2021 GMC Sierra 2500 AT4 with four-wheel drive below:
