Max towing package question

[06trdrew]

Hi guys,

I bought a used 2016 Sierra 5.3L, 3.42 SWB, Crew cab, which has the factory IBC and 12k max hitch installed. (I'm assuming it's a class 4 hitch but I have no marking on it other than 12k towing and 1200lbs tongue weight sticker)

How do I confirm that I have the Max towing package on this truck? Can I tell by the Vin# I'm curious if I can tow 11'100 lbs or 9'400 lbs Max rating. Thanks

I initially thought only max towing package only came with the 8 speed tranny and 6.2L option

Also, I beleive the RPO in the gloovebox should be NHT

Excellent information

I did not find the NHT like you mentioned in the glove box.

Although now that I have all these 3 digit codes I might start looking all these up to see what they all are

If you bought the truck from a GM dealer then they can run a build sheet for you.

NHT is the correct RPO for max tow.

The telescoping camper mirrors are the easy identification for max tow, they are in the package
