The mirrors are an option on half tons but makes sense they don't offer the dumbo ears on the high zoot Denali 1500.
However if that's your vehicle of choice then don't let the mirrors stop you. You can easily buy OE or aftermarket gm tow mirrors, even with most of all of the Denali features and new mirrors are not terribly difficult to install.
I bet Denaili HD truck mirrors would get you all the functions, but then again I get lost after power, heated, power extend, power fold, turn signal, running lights, puddle lamps, temperature sensor, espresso maker, etc. sounds like a $1000 bill when you crack one off on a fence post vs a few hundred for a plebeian power/heated tow mirror!
