I would be concerned that dry ice might make the plastic of the fridge brittle and subject to cracking. I would not do that. If you want to use dry ice, use it in a 50 dollar cooler.

Get an isolator or a relay. Set it and forget it. Just keep the TM plugged into the TV at all times.

I never forget to plug the TM back into the TV. After every stop I perform a walk around inspection. I am pretty srue I would notice the dangling cord. Every time I start the TV I turn on the headlights and verify in my rear view mirror that the lights on the TM come on. Then I turn off the lights. I also tap the brakes and verify that I do not get an Open Circuit warning.
