Keep the GMCs behind the tanks!
The AAGMC in the convoy is there to provide mobile AA fire.
We need to dig in those GMCs before the counter attack or
they won't last long!

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.
