Thank you for your help sgtusmc! I will definietely put up a post about that when I get to that phase of putting in another AC unit. I love the heater set up you have in your truck but my huge box would simply not allow for both AC and heat....I can roll the windows down but i cannot FREEZE!

i took your advice you put in a post a while back and have been getting around to working on my truck more lately with my break from school.....
thanks again for your help...
