FWIW.....I saw a very clever, simple, and inexpensive "mod" recently while
interviewing attendees at Syncro de Mayo about their favorite "Upgrades"

The mod was a muffin fan installed where the City Water Inlet was
previously.(how many times have you used that thing?)j

The inside of the black plastic thingy had been cut out and the fan
installed there so it would exhaust hot air from behind the reefer to the
outside....rather than just circulate it around behind the unit...like most
fan mods do.  He had a switch installed so he could shut the fan off at
night when camping if the noise of the fan was disturbing his sleep.  Also
a little short wire or string from the top screw to the flap to keep the
flap open when needed.

Owner reported significantly improved cooling efficiency in his fridge.
