now I can definately use this in Arizona and help save my marriage!!!
But I have a side door on the garage and just went to lowes and put a Security Metal screen door on the outside that locks on the handle and deadbolt. I usually just leave this open, lock the side door (and the RV gate outside) and crack the garage door on hot days. If it's really hot, then I run a heavy duty high powered fan to vent while the side door is opened and the garage door is cracked. Works great, but not everyone has a side door on their garage.
