Unless you have a 3-way fridge - which is found on many smaller TT and Pop-ups. 3-ways run on propane, 12VDC, or 110VAC.
Running off 12VDC, a 3-way the fridge will automatically draw from your converter supplied voltage (when hooked to shore power), Travel Vehicle (while connected for towing) or TT battery (no external connections). For long trips, 12VDC will save on propane, but keep in mind it will continue to draw power from both the TT and TV batteries when the TV engine is shut off.....
