Pittsburgh newbie to Jeepin' - my last 4x4 experience was in my '79 Bronco, 20 years ago, down in the mounatins of NC! I sold that while back in college, and have been stuck in cars ever since... until a month ago!
'07, and clean as a pin (was owned previously by a florist
who liked to travel to NC in it... a LOT - 67k miles right now), and Supperchipped, and getting a CAI installed TOmorrow. 
I've just done MOST of the 60k recommended maintenance on it. With full-time 4x4, transmission, diffs, and transfer case have all been flushed. Plugs and PCV valve are the last step to do in that process, and I already have them sitting in the console waiting to go.
Sadly, living near downtown, I'm certain the extent of my Jeepin' for the next few months will be, playing ARCTIC Commander in it, when the snow flies. I actually walk to work each day, so I rarely hit 7k miles in a year on my vehicles. My bosy and I want to set off for some wheelin' and campin' in the Alleghenies starting next spring, so I'll keep you posted on that!
Seeing as how I've ALREADY emptied every pocket to get 'er to this point
, here's hopin' she holds together long enough to get 'er out on some wide open trails!
, so I'll take some more of the fnished product tomorrow.
