Towing Mirrors on a new Silverado High Country or Denali

The extendable towing mirrors are part of the Max Trailering Package, available on Sierra SLT and Silverado LTZ. It is not available with the Denali 1500. Since you are looking at higher trim/equipment vehicles, I highly recommend that Max Trailering Package as it increases GVWR/payload also.

There are aftermarket towing mirrors available for about $200.
