Watch on YouTubeVideo summary
The video presents a comprehensive 4K walkaround of a pristine 2025 GMC Sierra 2500 Crew Cab Short Box, finished in Volcanic Red Tintcoat and equipped with the AT4 Premium Plus package. This heavy-duty truck features the powerful 6.6L Duramax diesel engine, which delivers 470 horsepower and 975 lb-ft of torque, paired with a robust Allison 10-speed automatic transmission. The vehicle is described as being in immaculate condition, having undergone a full safety inspection and service at Summit Auto, including a fresh oil change and topped-off fluids to ensure it is ready for immediate use. With only 14,145 miles on the odometer and a clean one-owner history from Illinois, the truck boasts a mirror-like paint finish that reflects its excellent state of preservation without any dents or dings.
Exterior details highlight the rugged yet refined nature of this model, featuring gloss black 20-inch alloy wheels wrapped in BFGoodrich All-Terrain T/A KO3 tires with significant tread life remaining. The AT4 package contributes to the off-road capability through Rancho shocks and a Z71 suspension system, while the exterior lighting includes bright LED headlights, running lights, fog lights, and tail lamps that are demonstrated to be fully functional. Practical towing features are abundant, including a full towing package with a receiver hitch, seven-pin wiring, telescopic tow mirrors with blind-spot monitoring, and an advanced camera system offering views from all angles, including over-the-top cameras for hitching and a trailer backup assist. The multi-pro tailgate includes step-assist functionality and a power drop-down mechanism with shock assistance to prevent slamming.
Moving inside the cabin, the interior is upholstered in black leather with distinctive Kalahari orange inserts and matching stitching on the seats and door panels. The front seats offer heated, ventilated, and cooled functions along with power adjustment and memory settings, while the rear bench provides ample space with its own heating elements and USB charging ports. The dashboard houses a large 13.4-inch touchscreen infotainment system that supports Android Auto and Apple CarPlay, effectively bypassing subscription fees for navigation by projecting phone maps directly to the screen. Additional interior amenities include a head-up display, a power sunroof, dual-zone climate control, a Bose premium sound system, and various driver-assist technologies such as lane keep assist and forward collision warning.
The presenter concludes by emphasizing the truck's exceptional cleanliness, noting that it has never been smoked and retains its original window sticker and windshield. Under the hood, the engine bay is equally clean, featuring the L5P Duramax engine with an emission sticker and a functional hood scoop. The video serves as a detailed verification tool for potential buyers, allowing them to assess the vehicle's quality and condition remotely before visiting the dealership. With its extensive list of standard and optional equipment, including the fifth-wheel and gooseneck prep packages, this Sierra 2500 is positioned as a highly desirable option for those seeking a capable, well-equipped diesel workhorse that combines luxury features with heavy-duty performance.

Hey everybody, this is Brett providing
you with the most in-depth and accurate
4K vehicle reviews and walkarounds on
the internet. Thank you so much for
choosing my video. I really appreciate
it and I hope everybody's having a great
day out there today. And I'm having a
great day, guys, cuz I get to do videos
for you of some of the best looking and
cleanest heavy duty trucks in the state
of Wisconsin. And this one is no
exception. This is a 2025
GMC Sierra 2500 crew cab short box. This
one has the AT4 Premium Plus package,
which also gives you the technology
package. And it is stock number 16735Z.
I am here at Summit Auto, your new and
used heavy duty truck headquarters. This
2025 GMC Sierra has the 6.6 6 L Duramax
diesel engine. It puts out 470
horsepower, 975 ft-lbs of torque, and it
is paired up with the Allison 10-speed
heavy duty automatic transmission. Now,
this truck has been fully safetied and
inspected by our service shop. Has a
fresh oil and filter change. All the
fluids have been checked and topped off
per the state of Wisconsin inspection
process. And this truck is 100% ready to
go. Really quick note, guys. I shoot all
my videos in 4K. So, if you have HD
capabilities on your computer, tablet,
or smartphone, turn them on now cuz it
is your best way to check out the
quality and condition of this truck
before seeing it in person. Let's get
started. This is a oneowner clean title
history, clean Carfax out of Illinois.
And speaking of Illinois, if you're
watching the video on YouTube, let me
know in the comments below where you're
watching the video from. I always love
seeing where our viewers, subscribers,
and future subscribers are watching
from. We get people from all over the
world watching these videos. And if you
are new to the videos and the channel,
welcome. Thank you so much for joining
us. What I'm going to do is go all the
way around on this truck. We're going to
go inside underneath, start it up. I'm
going to show you all the options and
give you the most accurate
representation I can of this vehicle.
Starting with the wheels, you get the
gloss black 20-in painted alloys. That's
part of the AT4 package. And this one
has BFGrich All-Terrain Tako3 tires.
These are LT27565
RT or I'm sorry, R20 tires. And I would
say they have probably about 70 80% of
the tread left on them. Uh really nice
tires, guys. I got the same exact tires
on my truck. So definitely uh good
tires. You got Rancho shocks there with
the Z71 off-road suspension package. And
uh
might be able to buy those from our
affiliate page, our Amazon affiliate
page that's linked in the description
below. We get a small cut, so that's
really cool. Front fender is in
excellent condition. You get the LED
headlights, running lights, and fog
lights. I will turn those on at the end
of the video so you can see just how
bright they are. Front bumper in
excellent condition. I didn't see any
major dents or dings on there. And you
can see it does have the front bumper
parking sensors and the painted front
rear bumpers. Get the kind of silver
grayish grill, 360 camera on here. Does
have the fully functional hood scoop on
there. I'll show you how that works in
just a second. And the hood is in
excellent shape. I didn't see any dents
or dings on there. You do get the cab
lights up top as well. And the passenger
side front fender is in really nice
condition, too. Passenger side front
wheel. No major scuffs or scrapes. This
color is called V volcanic
red tint coat. Paint coat is G&T.
It's got just a little bit of flare to
it.
Really a cool looking color. You can see
just how nice that paint is. Then as you
go down this side of this 2025 GMC
Sierra 2500, take note of how clean that
body is, how reflective and mirror-l
like that paint is. Once again, I take
these HD videos so if you are far away
or even if you're close by and you just
cannot make the trip down, but you're
still interested in purchasing the
vehicle, you can see the truck, hear the
truck, and have confidence in the
vehicle that you're looking at so that
when you get here, there's absolutely no
surprises and you can make a smart and
informed buying decision from wherever
you're at, or just make the decision to
come take a look at the truck. And if
this video helps you do either of those
things or both of those things, let your
salesman know that you saw the video, it
was helpful, and that Brett sent you.
Back wheels in excellent shape as well.
And the back tires have just as much
tread as the front tires. You get the uh
felt wheel well liners in this one. And
the underbody excellent condition. Has
all the remaining factory exhaust, which
is definitely what you want to see on a
diesel pickup truck. Hasn't been altered
in any way. And the lower rockers and
cab corners look great. You also get
these powdercoated
running boards on here. That's also part
of the AT4 package. You get these
sidebox steps.
You also have the lights and the
fenders. Those are pretty cool. LED tail
lamps as well. Coming around to the
back, you get the rear bumper steps. No
dents or dings on there. It does have
the backup parking sensors. Full towing
package, which includes a receiver hitch
and seven pin wiring. You also get two
auxiliary camera hookups there. And this
one has the multi-pro tailgate. So, has
the step assist in it. And it is a power
drop down tailgate with the shock down
assist so it's never going to slam down
on you. Comes with the factory spray and
bed liner, fifth wheel and gooseeneck
prep package. There's your handle for
that step assist. Four pin 7 pin wiring
as well as LED bed lights and 120 volt
400 W plugin. I'll show you how to turn
that on in just a second here. Uh spray
and bed liner goes onto the tailgate and
then the step assist goes like that.
makes it easy to get into the truck
and the tailgate shuts nice and solidly.
Coming around to the driver's side,
guys, just as nice as that passenger
side. No dents or dings on the box.
Looks really, really good. And for full
disclosure, this back wheel just as nice
as the rest.
Down the rest of the side of the truck,
cab and doors all look fantastic.
This one does have the telescopic tow
mirrors. They're heated blind spot
monitoring, LED sidelights, directional
signals. They power fold in, power
telescope out. We'll check that out in
just a second. Take a quick look at the
back seats. You get the black and
Kalahari orange inserts, leather
seating, latch child safety system for
any child car seats you may have. Power
slide rear window with the built-in rear
defrost. Headrest fold down for better
visibility if nobody's riding back. Here
you get those Kalahari
um accent stitching on there. You also
have inseat storage on the outboard
sides. These seats fold up. You got your
jack tools, all weather floor mats back
here. And these back seats are heated on
the outboard side as well. And you get a
USB and a USBC.
I believe that's an engine block heater
cord on the other side here as well as a
winter front. So that comes with the
truck as well.
Very clean in here. Door trim looks
good. Child safety locks on the back
doors. And the bottoms of the doors are
in fantastic condition on this side as
well.
Here's the VIN sticker. No Canadian
market trucks here. Trailering
information sticker. GM's nice enough to
give you that. And the tire and loading
information sticker up front. The AT4
Premium Plus package gives you the same
black and Kalahari bucket seats. No
rips, no tears on those seats. You get
the AT4 stitched into the headrest. Both
of these front seats are heated. Both
these front seats are ventilated or
cooled. And both these front seats are
power. Side current airbags, driver side
lumbar, factory all-w weather floor mats
up here as well. Uh you have your tow
mode, push button four-wheel drive, auto
headlamps, cargo lamps, head-up display,
tilt telescopic steering wheel and power
windows, locks, mirrors, Bose premium
sound system, and memory driver seat.
Got that cool trim on the door there as
well. And these mirrors do power fold
in. Now, I always like showing both
sides so that you know both sides are
working properly, which they are. And
then they do power telescope out and in,
out
and in.
Let's hop inside, check out the miles,
the radio, and everything that this one
has to offer. On the interior,
you can see this truck has 14,145
miles. You get the 12.3 in LCD display,
digital speedometer there, instrument
clusters, very nice and clean. You got
all your different uh radio options
there. You can also
uh check out everything on there. So,
instrument cluster is very nice and
clean as well. Range empty, all that
good stuff. Comes with the heated
leatherwrapped multi-function steering
wheel. On the right, we got Bluetooth
and information center controls. On the
left, you got cruise controls, forward
collision warning and gap adjust
controls, and your heated steering wheel
button. There's your shifter for that
Allison 10-speed heavy duty automatic
transmission. And this one comes with
the 13.4 in touchscreen radio. Now, this
one does have the navigation system
active on it right now, guys. I'm just
letting you know that these do require a
subscription. So, it appears that the
subscription is still active on this
one, but someday this could go away. Um,
just we have to disclose that. Um, but
not really a big deal uh because it's
got Android Auto and Apple CarPlay. Uh,
you got AMFM and Sirius XM radio
capabilities, Bluetooth, news, USB,
Alexa. Um, that's just how a lot of
things are going, guys. Is this um Apple
CarPlay, Android Auto, you can project
your cell phone to the screen. So, if
you got Google Maps on your phone, just
project it up there and it's like you
got nav on the screen without having to
pay for a subscription. Um, so you got
all that stuff. You also have your
cameras here. Uh, there's your backup
cam. You have a view of the back, a view
of the front, the surround view there.
You have this over the top front, over
the top back. You have the uh trailer
backup assist camera. That's my favorite
one. You can see which side your
trailer's on. So, if I'm backing up my
camper into the campsite, I can make
sure I'm not going to hit a tree or if
I'm putting my boat in, I make sure it's
going in straight. You also have the
curb cam so you don't wreck those nice
wheels on here. You have the
over-the-top hitch cam as well. And then
you also have the cargo cam. See what's
going on inside the bed of the truck.
So, a lot of great stuff you can do with
this radio, including the uh towing
stuff. Push button start, heated and
ventilated or cooled seat buttons, dual
climate controls, factory exhaust brake,
lane keep assist, parking sensors, power
drop down, tailgate, headlight stability
control, and downhill assist control.
So, here's a USB USBC plugin. your
keyless entry with remote start and a
power drop down tailgate as well. And
then your factory brake controller.
All right. You also have wireless cell
phone charge pad, a USB and USBC plug in
there, and then 120 volt 150 watt
plugin.
Trying to figure out how you'd turn that
plugin on the bed of the truck on. Uh
normally there was a there's a button
here, but this one doesn't have one. So,
I'll have to do some research, guys, uh
to figure out how to turn that on. But
anyways, you get the dual glove boxes
there. And this one does have the
original window sticker. So, I always
like showing that something I'm trying
to incorporate into these uh new or
these used car videos if they have a
window sticker is just to show you that
so you can see all the options.
Everything on here is your standard
equipment. Then optional equipment
starts with the AT4 premium plus package
which is a $4,35 option. Comes with that
technology package. The Vcanic red tin
coat is 645. The gooseeneck fifth wheel
prep package is $5.45 and allterrain
tires 295 and then trailer tire pressure
50 bucks. So total MSRP on this one was
$88,55.
So quite an expensive truck brand new.
Anyways, passenger side floor mat and
seat. Excellent condition. This truck's
never been smoked and smells very clean
inside. Headliner is absolutely perfect.
And you do get a power sunroof on this
one. Home link buttons for your garage
door, security systems, and lane
systems. Uh power slide, rear window
controls, sunroof controls, onstar, and
SOS. And this one does have the rearview
mirror camera, which will work once I
start the truck up here. Uh windshield
is in excellent condition. I didn't see
any chips or cracks on that. And it is
the original GM windshield.
Also has head head-up display. And let's
start it up and take a look under the
hood.
Starts right up. No check engine lights
or anything like that. There's your
head-up display in the windshield. And
there's your rearview mirror camera. So
that's a video display of what's going
on behind you. Now, if you didn't like
that, you can always turn that off. if
you can make it a normal rearview
mirror. But a lot of people really like
these cameras. Once you get used to
them, I don't think you'd want to go
back to the old cameras.
So, let's turn on all the lights here
so you can see
how bright everything is.
I would personally like to thank you for
checking out the video, guys. Thank you
so much for joining us. And uh hopefully
from this HD video, you've been able to
verify the quality condition options and
of course cleanliness of this truck
inside and out. There are those LED
sidelights to the back. They are very
bright as are the LED headlights,
running lights, and fog lights.
All working very nicely, as are the cab
lights. And under the hood, we have the
6.6 L Duramax diesel engine. This is
still the L5P engine, although the
upgraded horsepower, which they did in
2024,
uh, gives you 470 horsepower, 975
footlbs of torque.
Engine base, very clean, runs very
smooth, and once again, this truck has
been fully safed and inspected by our
service shop. Has a fresh oil and filter
change. All the fluids have been checked
and topped off. There is the emission
sticker. So, the air comes in that
opening, goes through a water separator
down the tube into the air intake right
there. And if you ever wanted to find
out where your paint coat is, it's on
this uh sticker right here, G&T.
And this truck is 100%
ready to go. I would highly recommend it
from a quality and condition standpoint.
I would ship this one back to Illinois,
California, Texas, New York, Florida. I
didn't see a single ding on it. Really,
really clean truck.
really nicely equipped as well. Just
about every option you could get. And I
think whoever's going to get this one's
going to absolutely love it. And to see
