2021 GMC Sierra 2500HD AT4 – Onyx Black

(Yes, the diesel-breathing, jobsite-owning one.)

This isn’t a truck. It’s a 2021 GMC Sierra 2500HD AT4 in Onyx Black — which is the automotive equivalent of wearing a tailored tuxedo… to a bar fight.

One Owner.
Local Trade.
Absolute creampuff.

Which is shocking, because this thing looks like it eats gravel for breakfast and washes it down with diesel.

AT4 Premium Plus Package - Translation: “You could survive in the wilderness… but you’ll do it in heated leather seats.” You get:

Premium interior that smells like success
Advanced trailering tech because 2500HD owners don’t pull lawn trailers
A stance that says, “Yes, I back into parking spots on purpose.”

X31 Off-Road Package - Because sometimes pavement is optional.

Off-road suspension
Skid plates
Hill descent control
The confidence to point at a muddy hill and say, “Bet.”

This truck doesn’t avoid weather. It waits for it.

Onyx Black Exterior

Black paint.
Black grille.
Black wheels.
Black attitude.

If Batman needed to haul a fifth-wheel camper, this would be it.

Heavy-Duty Capability - This 2500HD was built for:

Towing things that require paperwork
Hauling equipment that has its own insurance policy
Making half-ton trucks nervous at stoplights

And yet… this one?
Babied.
Locally owned.
Clean.
No nonsense.
No stories.
No “well, technically…”

It’s the unicorn of heavy-duty trucks:
Used for grown-up things. Maintained like it mattered.

The Vibe - This is the truck for someone who:

Needs real capability
Wants real luxury
And refuses to drive something that looks like it was built for a PTA meeting

It’s bold.
It’s blacked out.
It’s unapologetic.

And it’s sitting here looking like it’s daring you not to buy it.

If you’ve been waiting for a heavy-duty truck that can tow a house, climb a mountain, and still look flawless pulling into dinner…

This 2021 GMC Sierra 2500HD AT4 is it.

Just don’t park it next to anything boring. It gets judgmental.
