We got our 2010 with about 78K miles on it. I added an Air Raid MIT and had Black Bear tune it, leaving the AFM in for better mileage. I also added a take-out console so we could get some storage. It had the single battery, no second battery in this one. It was a supervisor's truck, that appears to have only had in-car lights and no light bar. Single spot. The rear seats looked like they were never sat in.
It's now more than 100K on the clock, and other than the usual stuff (p0446 and p0469 code repairs), plugs/wires and MAF clean, oil changes and new tires, it's run like a Timex!! It's my wife's DD, and she's on call every other day, so it HAS to run. So far, it has.
