I don't know the condiguration of your
refrigeration, but if the door opens at the front or side of the unit; then, each time you open the door all your cold air spills out and must be recooled. This might be worth the convenient access to the contents, but if you plan to be a cruiser and stingy with your 12V
power, you may wish to take this time of
repair in order to shift to a top loading refrigerator/freezer that will be much more efficient.
