Overall4Out of 5
  • Powerful, comfortable, and solid

    By Indiana Guy on Wednesday, November 27, 2019

    5.0
    My standard-sized cargo bed is huge! This truck rides and handles like a luxury car on the highway and the safety and vehicle information systems that are a part of the SLT Premium Plus Package are quite impressive. The 5.3 liter engine is more than powerful enough and super responsive when needed. Great truck.
  • Definite improvements but still behind (Denali)

    By LTOmaha on Monday, May 27, 2019

    3.0
    GM made some really good strides over previous models but ultimately didn't do enough, in my opinion. They'll likely continue to lose marketshare to RAM for this model generation. To start, I had a 2017 Denali before buying the new 2019 Denali and the improvements are dramatic. The most impressive include the brakes, suspension, and transmission. The brakes are solid and significantly improved over past model year. So much so they almost make you forget you're driving a full-sized truck. The ride on the Denali, which has the adaptive ride control, is impressive and makes the 2017 version seem like riding in a shopping cart with square wheels. Transmission (10 speed on the 6.2L) is ultra smooth and handles the 6.2L power transfer effortlessly and quietly, which is more than can be said for the rickety, tempermental, loud mess of an experiment that the 8 speed was in the 2017. The areas the 2019 falls short, however, are technology and interior. The Denali Ultimate edition comes with all the available bells and whistles. While the cameras and heads up display are impressive, the rest is not. The touch screen and graphics are sorely antiquated compared to the 2019 RAM 1500. There are no available auto sensing windshield whipers, no adaptive cruise controls, and the lane keeping system is whoafully inadequate for a vehicle in this price range. The instrumentation on the dash is clumsy and navigating the display options is frustrating and the opposite of intuitive. I drive a half ton pickup because my garage won't hold a 3/4 ton and it's side-load, so the turn is tight. The previous model year had a significantly smaller turning radius and the 2019 requires a 2-point turn to make it in my situation. Gas mileage is abysmal and nowhere near advertised. Even with the improvements to the transmission and the auto-stop engine, I'm still at least 5 mpg below prior model. Lifetime mpg at 6000 miles is 12.9 (no kidding).
  • Outstanding

    By Branta on Saturday, November 23, 2019

    5.0
    In every measurable metric, just freaking outstanding. The price is hard to take, but the performance, ride, braking and handling blow away every other truck I have ever owned. The LT2 6.2 Litre is amazing. Instant response and a ton of fun. Drive one and you have to own it.
