I just purchased a 2011 Sierra SLT Crew Cab, it has the White Diamond paint job with the tan casmere interior. Loaded interior, only thinks I don,t have is the rear camera and the cooling seats, just about every things else. It has the 5.3L engine had 43K miles on it when I bought. Have already put 300miles on truck getting 20mpg on highway, happy with that. Love the looks and feel of truck, hope I don,t have any issues with truck. If anyone knows of any I should watch for, let me know.
