Do I have a class III or IV hitch?

[ActingTruck]

18 GMC Sierra half ton. Z71 double cab SLE. 5.3,  3.42

 

The Window Sticker just says "Trailering Equipment Package"   The hitch is a 2 inch but even with what I think is the code (Z82?)  my feeble googling did not find me the answer.

Class 3.  Class 4 are 2.5".

Class 3.  Class 4 are 2.5".

Class 3 and 4 are 2”x2”. The difference is tongue weight. Read this https://www.reese-hitches.com/learning_center/general-towing-classes

You are correct, V is the 2.5 inch receiver, IV is a weight distribution set up. III comes with the truck from the factory with your Z82 tow package which has the 2 inch version.
