To clarify, if is mandatory that you run the refrigerator fan when the TM is down. This may have something to do with cooling, but the main reason is to prevent heat buildup between the walls, as in the down position there is no venting. If/when you do get your TM, open the outside refrigerator vent doors and locate the vent duct. It is about 2" or so in diameter and is a flexible plastic. Follow it down and look under the TM to see where it comes out. With the fan on, place your hand over the duct exit and make sure the fan is sucking the air down and out. There have been reports of the fan wiring being reversed and the fan blowing air UP, which doesn't help in exhausting heated air! Basically the only time you will use the fan is when the TM is down, although it's use may help cool when the outside temp gets over 85 degrees.
Seems to me from reading this forum that most people power their refrigerator on 12v battery when travelling, propane when dry camping, and 120v when connected to shore power. This might be an interesting topic for a poll for anyone who knows how to set one up!
