Previously owned a 2001 Suburban, as my sig below shows, we have two GMT900 trucks.
The Suburban has been absolutely amazing and trouble-free. Less than $100 in repairs over the last 5 years.
The Sierra Denali has had some repairs - front half-shaft and wheel bearing, rotors warping (I believe the half-ton trucks are underbraked).
Both trucks are superior in just about every way to my 2001 Suburban. Neither one has a single crack in the dash, but the Denali had two of the door handles do the razor blade trick. Cheap and easy to replace.
And the 2500 is a superb tow vehicle. Yes, in absolute terms, it's not as good as an GMT800 with the 8.1, but it moves my 900-lb family of 5 and 8600-lb trailer just fine, including the high passes in the Rockies. I'll happily sacrifice a little towing capacity to have my 4 heated seats, power tailgate, remote start, heated steering wheel and other nice goodies.
