Do you notice the exhaust heat from 12v refrigerators in the bronco cab 4d or 2d? Does the AC fight the frig to keep the cab cool on a hot day?

thanks.

A 12V car fridge will have its own internal compressor so the Bronco's AC will not be affected at all by running one.

There should be very little heat coming from the vents on a 12V car fridge. The fridge will circulate air and as long as the fridges vents are not blocked, it will not cause any issues at all..

The fridges compressor will not constantly run. If it's pre-cooled to temp and stocked with already cooled items the fridge will probably only run for about 10 minutes every hour to maintain temps.. Maybe more or less than that 10 min depending on the fridges temp setting and the ambient temperature.

Mine runs 24/7 for days on end when out on camping and 4 wheeling trips. Last summer I was on a 4 day trip where temps were in the high 90's and I had no issues at all when out wheeling or back at camp..

Thanks, I can do the BTU to CF with 2nd law consideration math, however that's not going to give me real world Feeling. I mostly run in the desert, and it can really get hot! When will auto makers put in solar powered vent fan systems in the roof of cars? I may install this in the roof.
