Has anyone used one of those 12 volt coolers that plug into your cigarette lighter adapters? I'm thinking about leaving one plugged in to the rear "always-on" cla, but I'm concerned about running the battery down.
Yeah .. picked up one from Target .. Coleman ($19.99 .. normally $49.99?) a few months ago just before a trip .. worked great! Although I didn't leave it plug'd in over-nite .. keeping it sealed .. kept the drinks cold (w/o power to it)
