Got my hands on a 2020 Silverado 2500hd! Long awaited for me for sure, seeing that they are making their way on to lots. Lets start! Exterior: This particular truck I drove was a Work Truck. In person, the HD is much easier on the eyes, but the WT is, I feel, the least attractive. I think its the black grille treatment that puts me off. This truck had the 17" carryover steel wheels, wrapped in LT265/70R17 Firestone TransForce AT tires (yes, the carryover AT not the AT2). Options list was minimal, including the WT Convenience Package, Integrated Trailer Brake Controller, the AT tires and black bowties. Overall, the truck's exterior is very functional. The bed steps are genius. Sure, they don't tuck away like some aftermarket designs do, however as a result they maintain bed rocker ground clearance like there isn't even a step there. Now, I am personally not a running board guy, mainly for looks (and I think 1/2 tons and Colorados are too low stock for them), but this thing needs them! Definitely an increased step in height with the T1 over the K2 HD. Its noticeable. Also, the size increase is noticeable too. I think its within an inch or so height wise to a Super Duty, and the body is just as wide as one. They dwarf the K2 HD. I do think that the 18" wheels are a must for looks, as they run a 33" tire and suit the truck's profile much better than the 17" wheels do as a result of the 31.5" tire they use. The towing mirrors. Totally functional. I can definitely get behind the way they are mounted once you drive one. This one had the base tow mirror, so just heat and power upper glass. There is much better visibility in the A-Pillar to mirror sightline. I found the extending not what I thought it was going to be? Its actually positionally detented. You pull it out and it comes off the arm a touch and then hits the outer detent. No "in between" position, but that might be just because its the base mirror. Oh! Another interesting fact. No aluminum body panels anywhere that I could see. Its all steel. The hood, doors, tailgate, all steel. Honestly, I was expecting some aluminum somewhere, like the hood at least, maybe the doors. GM wasn't joking when they said it only shares the cab structure, otherwise everything was unique to the HD. The biggest giveaway to those keen enough to notice, is the "CHEVROLET" area on the tailgate. Its nowhere near as protruded on the gate as the 1500 gate. Interior: See 2019+ T1 1500. Don't expect anything different here. Its still a good interior ( I think), apart from some questionable material choices in spots. I will add one important bit. Anyone looking at a WT or Custom trim HD, make sure you sit in an LT or higher with a power seat. The hood is even higher yet than a K2 HD, and the tall front at the end of the hood can be a bit tricky. I'm 5'10" and felt the standard seat to be ok, but some more height would have been nice around a parking lot/close to other cars. The mirrors, see the exterior description above. Powertrain/How it drives: The big bit. This truck had the 6.6 L8T gas V8. For being as large and heavy as this truck is, that powertrain is much improved over the L96, and long overdue. I didn't time anything, but it can move quite well when you want it to. I pulled out from an intersection normally, hit 2nd gear and rolled right into it and it took off quick. The K2 HD dead feeling accelerator pedal is gone too (thank god) and the power feels in line with your right foot. Much better response. Mileage wise, I averaged 15mpg, I'd say 65/35 city-highway split? Even the 6L90 shifting is improved. Do I still hope they throw the 10L90 in it? Yep. But the 6L90 has been a strong unit, and the added power makes it a good package for the time being. The added wheelbase smooths the ride out a touch. Stiffness? Well, its an HD LOL and had 80psi in the rear tires, but it was still well behaved. Overall, a nice improvement on the K2 HD. Love the mirrors, love the power, the bed steps all around. Love the look more or less, could use some interior help for sure. Big thanks to Cavallaro Neubauer Chevrolet in Williamson NY for letting me borrow this beast!
