What people say
Great options and exceptional value. Couldn’t be happier
I’m not a fan of black. This truck had a black exterior and interior. It’s not for me. GM should offer more color choices.
Great reliable truck highly recommend to anyone looking for a great all around Truck
I test drove all of the major diesel 3/4 ton trucks and this one rode the best and had the most creature comforts. That coupled with a reliable duramax and allison transmission sealed the deal. It also proportionally looks right. Some trucks just look off (too low, too high, tires too small, etc).
This truck is an SLT model, so its loaded with a lot of luxury features including power leather seats, premium sound (Bose), factory remote start, heated and cooled seats, heated steering wheel, etc.
