I love my Duramax trucks 16-18 local and well over 20 hi way.
It will pull anything u hook to it.
A perfect vehicle would be a Duramax/Allison H2

.
My dealer said the Suburban 2500 will get Duramax in 04, Hummer next????
This is my 5th Duramax and I have a blue GMC like this on order.
I don't like the front on these as well as old HD or the GMC also when I get mud or stones down behind the plastic on the top of bumper and it pushes it out

.
Since I work for GM and get discount I can sell these or trade after 6 mon. and usually get what I paid for it.
Who wouldn't want to buy a $47,000 msrp for $35,000 w/5000 miles.
I pull a 14,000# trailer and NO problems, in fact if u want to pass someone u can do it.
