Chevy Avalanche Z66 VS Z71 Package?

[jorge]

What is the difference?

Is it true that the Z66 has Autoride Suspension and when tow/haul mode on its stiffer for towing/Hauling?

Can the AV have both G80 and Traction control?
And is it true that if you put carbon monoxide instead of air in the tires they would perform better their 275/55-R20?
Whats the code for Electronic brake distribution?

Tow/Haul mode changes shift points in the transmission do you don't pull in the final drive- has nothing to do with suspension.

Carbon monoxide in a tire for performance- Um..... Not True.
