Anybody still tow with an old GM?

It was the heated steering wheel and the 6.6 gas that does 40% better than the 8.1 in fuel economy.

Heck yes, 8.1L mated to Allison 2100, just 26K miles, tows without issue here in the mountain west and four corner states. Both the Allison and 8.1L are easy to service and maintain, works for us as I prefer to do the work myself.

They aren't common but I see those years all the time in SoCal.

You mean GMT 800, not 900...but
Can’t swing a dead cat without hitting one around here. And many of them in good shape. That’s the difference between the rust belt and the rain belt!
Even a lot of 400s around here still, most of which are half scattered down the ditches in small rusty flakes and half in a boneyard back east.

Anyone who wants a straight rust free, generally good paint too, old truck, can buy basically any model that “needs” a trans, engine, whatever out here for pocket change.

If I lived back East, I’d have a couple from here and then just find the good mechanical parts from a rust belt truck that rotted out before it wore out!

07 GMC CC dually Classic Duramax here just shy of 190K and going strong

I have one of those rusted out brake line examples sitting in my garage in MD. Been there 3 years now. As long as they salt the roads in the winter up North you will have RUST
