you can avoid getting the moldy A/C smell by: always use max a/c as it recirculates interior clean/already cooled air. before reaching your destination (5 mins.) turn the a/c off, turn on the rcirculate button and fan on 3, this will dry off the cooling coils hindering mold growth. i have 50K on my Frontier,-no smell, this has worked on every car i've had.
think about what that moisture does when you turn off your truck in 90 degree weather and it sits,...it grows mold and mildew...eventually..
