You should also get used to the fact that the climate control system was designed for a single cab, and is woefully inadequate on the doubles.
This is most apparent if you have four people in the truck in winter (for instance, going to the rink). The climate control system is completely overwhelmed by any moisture in the cab.
Expect icing on the inside of the windows and lingering high humidity if there is any snow tracked into the cab.
The climate control system is weak, weak, weak.
