Well chaps, I've had a couple of issues with the Suburban, which I use for work, so down time is not an option. I've acquired a Duramax Silverado but decided to keep the 'Burban. It's been a great truck and will be perfect for the girls when they start driving. The 6.5 seems to keep going and going no matter how hard I or the previous owners tried to kill it. This forum is the best I've seen and plan to continue to visit regularly.
