I also have a small mini-fridge in the car, highly recommend!
The next item I've been thinking about installing is a Keurig single-cup coffee maker. Unfortunately their large ones draw 1400 watts, the small one is only 700w but needs 3 minutes to run. 700w / 12v = 58 amps. Not going to be a cigarette lighter affair.
Re: scanner in the car, Florida has a similar rule -- OK for ham radio operators to have a scanner, even with the scanner set to police freqs.
