 Hey, this is Brett and this 2018 GMC Sierra 3500 Crew Cab Long Box Dual Rear Wheel Denali is stock number 12641Z. We are here at Summit Automotive in Fond du Lac, Wisconsin, your new and used heavy duty truck headquarters. This 2018 GMC Sierra 3500 has the 6.6 liter Duramax diesel engine. It puts out 445 horsepower. This truck has been fully safety and inspected by our service shop per the state of Wisconsin inspection process. It has a fresh oil and filter change, all the fluids have been checked and topped off, and this truck is 100% ready to go. We're going to go all the way around, inside, underneath, start it up, and take a look under the hood in this video. Red Quartz Tin Coat is the color. We shoot all of our videos in 1080p, 60 frames per second, so if you have HD capabilities on your computer, tablet, smartphone, or television, I highly recommend turning them on right now because it is your best way to check out the quality, condition, and cleanliness of the truck before seeing it in person.

This one comes with the polished aluminum rims, and it has Milestar Patagonia AT tires, these are LT 235 80R 17s, and they got a pretty good amount of tread left, I'd say probably 70% of the tread left on those tires. Frame and underbody is in really nice shape, other than being a little dusty. Front fender, not too bad, those have one little touch-up spot there. Has the LED running lights, projector lamp headlamps, factory fog lights, front bumper is in pretty nice shape, there is one little ding in the middle there. Front bumper parking sensors, you get the chrome trimmed grille, this one has the true cowl induction hood that's fully functional, and I'll show you how that works in just a little bit. You get the cab lights up top, passenger side front fender is in nice shape. And the passenger side rim, no major scuffs or scrapes on there. As you go down this side of the truck, take note of how clean the body is, how reflective and mirror-like that paint is. We take these HD videos so if you are far away or even if you're close by and just cannot make the trip down, but you're still interested in purchasing the truck, you can see the truck, hear the truck, and have confidence in the vehicle that you're looking at before you even get here, so when you do get here there's absolutely no surprises, and you can make a smart and informed buying decision from wherever you're at. And if this video helps you make that decision, let your salesman know that you saw the video that was helpful and that Brett sent you. Back rim is in excellent condition, the back tires have just as much tread as the front tires, and the frame and under body, like I said other than being a little dusty, is in really nice shape. It's all remaining factory exhaust, cab corners, and lower rockers all look really good as well, and it comes with a nice set of factory chrome step bars. Dually tub is in pretty nice shape, coming around to the back, you get the painted rear bumper, rear bumper parking sensors, full towing package, rear bumper steps, receiver hitch, 4-pin and 7-pin wiring. The tailgate is in nice condition as well, I didn't see any dents or dings on there. Has a shock down assist, fifth wheel and gooseneck prep package, and you also get LED bed lighting up there, 7-pin wiring, and then the LED bed lighting is on that side as well. Got some side box tie downs, and that tailgate shuts nice and solidly. Going down the driver's side, this dually tub is in pretty nice shape, does have one little touch-up spot there, got a couple little rock chips that have been touched up too, but that's why we do the videos. Back rim is in excellent condition, and down the rest of this side of the truck, doors look pretty good, has the telescopic tow mirrors built in directional signals, LED side lights, they do telescope out like that, I believe they're power folding as well. Inside, the Denali package gives you the tan leather interior, there are no rips or tears on the seats, you get the Denali stitched into the headrest, and the seats are in really nice shape. Factory floor mats, auto headlamps turned out four-wheel drive, factory brake control, you get tilt, telescopic steering wheel, power windows, power locks, power mirrors, memory driver seat, and like I said, these mirrors do power fold in. I always like showing both sides, so you know that both sides are working properly. We'll hop inside, check out the miles, radio, and everything that this truck has to offer on the interior. You can see that this one has 51,547 miles, you do get a digital spinometer, instrument cluster is very nice and clean. It comes with the leather-wrapped heated steering wheel, Bluetooth and information center controls on the right, cruise controls, heated steering wheel button, and forward collision warning controls on the left. It does come with the Allison six-speed automatic heavy-duty transmission with the optional tap shift, and this one has the GMC IntelliLink radio, AM, FMN, Sirius XM radio capabilities, you can see it does have the factory navigation system on it, AM, FMN, Sirius, and then you have your projection manager where you can project your cell phone to the screen via Android Auto or Apple CarPlay to play music, media, and you can even put your own navigation system on the screen, it's pretty cool. CD player, heated and cooled seat buttons, dual climate controls, power pedals, stability control, that's for your cargo lamps, also for your LED side lights, and bed lighting, parking sensors, lane departure warning, and factory exhaust brake. You get two USBs, two 12-volt power points, and then a 110-volt, 150-watt plug-in in here. Cell phone holder, it also has the cell phone charge pad, passenger side format and seat are in excellent condition, smells very clean inside this truck, I don't think it's ever been smoked in, and the headliner is in really nice condition as well. You do get a power sunroof, map lights, home link buttons for your garage door security systems and lane systems, and sunroof and power side and rear window controls, on-star and SOS capabilities in the mirror. We'll take a quick look at the back seats, and then we'll start it up and take a look under the hood. Back seats are in excellent condition as well, does have the latch child safety system for any child car seats you may have, power sign rear window with the built-in rear defrost. These seats fold up for extra storage, and the carpeting and floor mats back here are in nice condition.
