How do you change cab air filter on gmc c7500?

Oh, dude, changing the cab air filter on a GMC C7500 is like a walk in the park... if the park was full of confusing car parts. Basically, you locate the filter housing, pop it open like a can of soda, swap out the old filter for a new one, and voila! You're breathing clean air again. Just make sure to not accidentally install a slice of Pizza instead of the filter... that could get messy.
