I am looking at used suburbans. 2500 series are extremely rare around me that aren't stripped down government models. I don't need leather, but don't want vinyl. The 6.0 seems like it was only available in the 2500.
I was just wondering if the 6.2 is worth it over the 5.3, which has served me quite well. And yes, the powerband is up at 3500-4500 Rpms and you have to be willing to use it or will complain about towing performance.
Thinking I will stick with the 5.3 unless I find the unicorn 6.0
