(Which was discontinued when the current Silverado came out)
So there is it: a new option pack. Which turns the current Silverado into an "Almost Avalanche".
And why not.
It doesn't look bad.
Here is the official claim:
"The High Desert package blends the capability and utility of Silverado, with the refinement and luxury of Suburban".
Which does sound like a lot of PR BS to me.
As after having driven both, I can tell you that the Suburban is not really more refined or luxurious than the Silverado.
But hey, that's marketing for you...
