We bought this truck used at 60,000 miles and have had very little trouble with it. I wanted something that could pull my horse trailer over mountains with no problem and it more than delivers. The 2500 model / 454hp engine is outstanding! Having the rear A/C is essential with people in the third seat in the summer. We are and will remain a Suburban family! My last Suburban (a 1979) went to almost 300,000 miles on the original engine. GMC certainly does make a GREAT truck!
