Grandpa Motor Company. This truck is the truck you most often see in 2 wheel drive. The new Duramaxes are made for old men who like to drive their trucks once a month and never take them offroad. New GMCs dont have a solid front axle making them damn near offroad incapable.
Duramax is a great engine. Isuzu did a good job there. Fuck duramaxes i'll smoke any duramax in my ford 6.0 powerstroke.
