GMC's Denali-badged vehicles - Denali meaning "the high one", referencing Mt. McKinley - have always been the Cadillacs of trucks (except for Escalades, which are actually Cadillac trucks).
Sitting somewhere just south of Premium Luxury, Denalis have always provided buyers with well-equipped, more luxurious versions of GMC's regular lineup. For 2011 the General will be releasing the Sierra Denali HD based on the GMC 2500 (3/4 ton) and 3500 (1-ton) Heavy Duty models.
