You wouldn’t have to remove the fridge, just the outside vent cover behind the fridge. Is it a 3-way fridge (gas, electric, battery)? If so, the fridge and fan probably pull a solid 14-16 amps going down the road and they are on the same 20 amp fuse. If you added your mini fridge and had it cooling while going down the road, you’re likely to blow the fuse (not to mention kill the battery quick).

Maybe go a little further and tap into the 12V circuit coming off the water heater ignition? That’s a 20A fuse, and it’s shared with the CO/LP detector and the radio antenna (power is killed to both while going down the road) along with the storage lights under the bed. Those are all pretty low draw devices.

Is there an empty fuse slot? If so and you’re really feeling adventurous, run a dedicated power supply. Folks have managed to fish a wire under the bathroom floor from the power center to underneath the cabinets.

Here’s a pic of the 12VDC side of the schematic.
