2018 GMC Sierra 1500 SLT -- Spacious cab with plenty of power under the hood.

I have owned my 2018 GMC Sierra 1500 SLT for a couple months now and I really enjoy it. Starting with the interior, I bought the crew cab which is very spacious & comfortable for people riding in the back. The rear seats fold up (if needed) with 60/40 split. The front seats are powered heated seats with the option of two memory settings. The center console is very spacious with a 2-cup holder, an integrated phone holder, 3-prong power outlet, 2 USB ports & 12V port. The display is a nice size for the infotainment system which allows you to utilize Android auto & Apple CarPlay. Overhead console has a universal garage door opener feature, along with a switch for the powered back window. The instrument panel is not overly clustered or lacking like I've seen in over vehicles. The exterior of the vehicle is eye catching; I have gotten plenty of compliments on how nice looking my truck is. The body of the truck has a somewhat aggressive look but also feels luxurious at the same time for a pick up truck. The 20' wheels fit nicely on the truck & help give it a nice stance. The engine has nice power to it when not towing but the acceleration of the pedal travel to engage acceleration is not the best but when you put your foot down on it really good, you feel the power from the engine. I'm really enjoying my truck and I look forward to driving for years to come.

Lots of legroom, comfortable seats, rides smooth, safe, and looks good.

I love my GMC sierra. It is large and roomy. The back seat has a lot of space, which is great when you have a car seat or two back there. I am able to have a car seat on the one side, fold up the two other seats, and change my child's diaper. I am confident that I could fit 3 car seats comfortably in the back. I haven't had any trouble with any of the technology that the truck comes with either. I was rear ended, and besides the bumper, the truck, me, and my child were all 100% fine and that to me is worth everything. Nothing has been wrong with it so far, besides routine oil changes. We have the OnStar feature, which is great. Another thing I love is the seat memory, and heated seats and steering wheel. Overall a fantastic truck. Drives smooth, and has tons of cup holders/ storage. The only reason I would ever get something different is if I needed more seating. I would still get a gm though.

The GMC sierra is an awesome drive and ride.

This is a very comfortable ride. We love the heated seats and steering wheel. Seats can also be set to cool. The seats have. Lumbar support that helps on long drives. Back seat is spacious and comfortable. Pulling our 5th wheel trailer is very easy. We hardly notice it behind us. This is a diesel and I think it has more power than a gas vehicle. We were pleased that our mileage is about 13 miles to the gallon when we are pulling the fifth wheel. We have gotten as much as 23 miles to the gallon highway driving without the 5th wheel.
