Tow package

Most manufacturers have towing guides and other documentation available online that shows what various packages include. My Sierra for example had an available towing package, which mine has, and an HD towing package, which I do not have. To top it off I have the Z71 off road package which adds a couple of components that are included in the HD package. Clear as mud!

Depending on OEM packages the towing capacity can vary by several thousand pounds. In other words, not all towing packages are created equal!
