prevent "wet stacking" with the heat or air conditioning running
all night
while they sleep it off. What? None of them?! Hmm......

Sounds like you need to get your ears recalibrated.

In Alaska, it's so cold in winter they never shut them
off.....well, maybe
will now that fuel oil is headed for $10/gallon....

My father never shut his truck off except for oil changes from
November to April, and he was a long way from Alaska.
