My truck camper has a 3-way refrigerator. Works fantastic on propane and 120v....but on 12v it has a hard time staying below 40 degrees. The factory wire feeding it 12v is about 14g or 16g. Would r...

It is three way....The switch on the front offers 12V / 120VAC / Gas
I just found this article:
Refrigerator: The 3-way refrigerator in most RV’s like the Oliver can run off of 12V DC, 120V AC, or propane. While running off of DC, the Oliver’s refrigerator requires a massive 15 amps of current (contrast that with the less than 2 amps required with 120V AC). To handle a 15 amp load, the refrigerator specifies 10 AWG DC wiring and maximum wire length of 20 feet.
This heavy current draw is why you should never leave a 3-way refrigerator running on DC power while stopped. The fridge can drain your trailer battery in just a matter of a few hours – and if your tow vehicle lacks a battery isolator circuit you could find that battery dead as well after a long lunch!

Guess I need to do some rewiring!
ok. So you're sure of your battery?
