We got our Duramax in July and are absolutely in love with
it!
It is getting 20 around town and 15+ towing a 3 horse
gooseneck LQ loaded.
My favorite part is the Allison with the tow haul button …
it is a “smart” transmission and will hold the trailer on downhills
without riding the breaks.
It is just like having a manual for downhill.
We don’t have a single complaint after several big
trips.
