Only thing i didn’t like is the gas mileage. Mine is slightly lifted though and averages about 13 miles to the gallon

2018 GMC Sierra. Simply the best driving & riding truck I have ever owned. The magnetic ride sets it apart and was the reason I purchased a 2018 vs the newer body style without it. It’s also the reason I choose it over similar Ford and Dodge trucks.
