My truck has the Z66 sticker on the side of it, but it is not listed in the RPO codes. Is there a way just by looking at (under) the truck to see exactly wheather or not I have the Z66 package?
 
See if it has a G80 RPO code
 
It should have Z66 in glovebox

yes as it was an option like Z71 or other.

Look for big fat Shocks in rear when I mean fat diameter.
