Being a pretty good mechanic and maintenance freak, I should be able to keep it on the road for a while. I guess the one thing I worry about is will the engine and trans with over 100,000 miles typically be too worn out to tow well? (I know it depends a lot on maintenance). Is the 4.2 I6 considered a truck engine?
As I said above join gmtnation.com. Big help, lots of knowledge there and lots of willing helpers.
I towed with mine up to 160k. The only reason I sold it and got the Sierra was that I was very marginal on towing capacity with my current trailer and was looking at about $1k in maintenance over the year, things like exhaust, etc. and I just didn't want to stick any more money into it.
Yes the 4.2 is a truck engine. It was designed from the ground up to be only used in GM trucks. Doesn't matter that they never put it in the full size trucks. At it's introduction it had about 80 more HP and torque than the 4.3 V6. Using it in full size was part of the original intent but being an OHC engine it was expensive to build. The newly redesigned 4.3 has closed that gap.
