We own a 2016 RW39mb with Whirlpool french door residential refrigerator. Question, how is power provided to refrigerator when RV in tow connected with 12 volt power from tow vehicle.
The truck feeds 12vdc power to the trailer batteries thru the pigtail connector . The trailer batteries feed 12vdc to the inverter which converts the power to 120vac. The inverter feeds the electrical outlet to the residential refrigerator.
It appears the refrigerator is not operating during which time the truck is connected to RV. I've checked the input pigtail connector at RV, power is provided and the RV battery disconnect switch is ON. Is there additional switching required at the RV fuse and circuit breakers?
Did you check to see if the inverter is on? It can be turned on/off at the meter.
Are you batteries ok? The inverter only needs the batteries, not the truck.

This was the problem i had on my first trip with the RW.. Now I know to verify that tge inverter is on before each trip.
Thanks to everyone for responding and providing valuable information. My problem is no longer. As suggested the Magnum MMS 1012 inverter was off at control panel, once depressing the ON button all is working as required.
New Question, do you turn inverter OFF when connected to shore power?
Again thanks for the input to all your suggestions.
There is no need to. The magnum has a built-in transfer switch. Its purpose is to sense if you have shore power. If so, it sends the 110v straight through to the refer. If not, it pulls the 12v from the battery and inverts it to 110v to power the refer.

I asked the same exact question when I was new, and was told to just keep it on ... like Ron Popiel does, "set ot and fotget it" ...
Our inverter has never been turned off in the two years we've had this 39MB. So if the Camp Ground were to lose power while we were away, the inverters and our battery bank would take over and supply power for several days if needed.
That's funny Michelle, our inverter has never been turned ON except for the day after we bought it while we travelled! But you do make a good point about power failures.
After learning by trial/error how efficient our residential fridge is, we don't use 110V at all when towing. We've been disconnected for as much as 12 hours and still have full ice cubes in the freezer.
