It's approaching 300k miles and smokes a bit, but the POWER!! I pass a lot of Dodge Rams going up hill.

Is my truck really 18 years old now?

(Ack!!)

Time flies doesn't it? Hard to believe these trucks are getting that old already.

I probably should have mentioned I keep mine on the hot street tune where it's gotten 20 highway. I could probably move it to the tame tune and squeak more but never tried.
Towing I use a tow tune that pumps up the power a tad but still easy on the trans.
And yeah, the pulling power going up the mountains is hilarious. Just use cruise control and it never slows down or even downshifts. Puts my old 79 1 ton with a 454 to shame. That's the sole reason I bought the darn thing.

I was hesitant to comment on the thread, because of the age of my truck.

Don't feel bad. I bought a brand new Harley a few years ago and it turned 22 on June 5th...
I bought my Silverado at 4 yrs old a couple yrs ago and it's now 11 yrs old. How the heck does this happen ???
