I have a 2012 184BH, it has a new to me 3 way fridge with a dial to select shore power, 12 volt, or propane. My trucks trailer plug will charge the battery when running or draw off the trucks battery when turned off. I guess I'm wondering how well these work on 12 volt and how long they will run? I mainly travel in my camper and drive all day and stop overnight like at a walmart and hit the road again the next day. I figured it'd be a power hog. I just wondered what all you guys do. Thanks in advance.

Mainly dry camp leave propane on all the time.Only remember the low DC light coming on once.We have the model 1210 Frig, what has helped was adding interior 12V fan to circulate cold air. Thanks
As the 12 volt is like the 120 AC current, they both are heating an element. Your batteries will not last long with the fridge on 12 volt. A trailer we owned in the 1980s had a 3-way fridge. I tried using it on the 12 volt and after towing for three hours, the trailer battery was almost dead.
The dealer said the fridge sucked more power than the TV could provide. Not sure if that was true.

They are power hogs when on DC. I previously had Class B rv's. They all had 3 or 4 cf 3-way refrigerators. DC power is very inefficient way to cool a fridge. 1 to 2 hours will cook a battery. When I had the Class B's, I'd put the fridge on DC while we were driving. It was enough to maintain the temp. Once I stopped, I'd switch to either propane or AC depending what was available.

Last three way fridge I had could be powered by the truck when we were towing, but the trailer battery won't power the fridge overnight. Also, on 12v it would "maintain" a cold temp, but couldn't cool the fridge.
Best bet, use 120 or propane when stopped, switch to 12v when towing. Too many people will tell you to just go ahead and use propane while towing, but it's illegal in places, and always dangerous.

I happen to have all the manuals stuffed under the dinette seat so I looked this up for a Norcold 2.7cf size fridge (ours is 2-way, not 3-way, but the manual includes specs for both). According to the manual the 2.7cf DC model requires ~12-14amps to run. They also state to use DC power only AFTER the contents of the fridge are completely cooled and ONLY with the vehicle engine running while in transit.
