Looks spiffy! You're right around the corner from plus a few miles. I've had my 6.2's for quite a while - Sub more than a decade. Cheap parts, easy to work on, easy to diagnose, good mileage but a little wanting in the power department. Not bad but could be better.
Good luck and have fun. You've come to the right place for GM diesel info.
