HD, or not HD ???

I heard some 1500 Silverados are Heavy Duty and some are not.

How do you tell if a truck is HD or not HD?

Mine is an LT and is supposed to have the towing package, so does that mean it's HD?

I have a 2006 1500HD.

Crew cab short bed, 6.0, 4l80, autotrac t case, 9.5"SF rear, 9.25" front, and 8 lug.

They are definitely a real thing
