snyps:  Congrats!  You'll love it!

 

moo snutz:  If you have the 8.1L, how do you not have the Allison?  Do you have

the 6 speed manual?

 

 

 

 

 

Yeah, I had to special order the truck. I didn't find a single 8.1 / 6 speed combo when I started looking. I think I would have liked the Allison but it's a pretty $$ option.

 

snyps - You're gonna love the 8.1 !!

 

:D

Hello all, I am a new member. I have an opportunity to purchase a 2002 Chevy 2500hd ext cab LS with 8.1/ally. It has only 38k. Absolutely no rust.(in Cleveland) They want 12,000 for it. I am concerned over gas mileage. Will do some towing. Some work driving. Seems like a deal I should not pass up. However, might I be better off looking for a basic Silverado with a 5.3?? Thanks gang, PistoPounder

do you know how much you will be towing, weight-wise? my '04 Sierra 3500 with a 6.0/4L80E sucks for gas mileage, the 8.1 is gonna be worse, but it'll tow better.
