Thanks for all the reply's a lot of good suggestions on the forum.
The fridges in high wall A-frames and PUPs are more like small RV fridges than the fridges in the standard A-frames and PUPs. The High Wall models are thermostatically controlled and have a DC control board and are auto-start on propane.
Fridges in standard height A-frames and PUPs are continuous run with no thermostatic control (there are dials on AC and propane that set the amount of fuel/power used), and are manual start. They can be difficult to start on propane at high altitudes, but cool just fine.
For the OP, write down the fridge model number and download the fridge manual from the Internet. That will tell you whether or not your particular fridge will automatically shift to 12V DC - many RV fridges do not. Usually, the Auto setting will switch to propane if 120V is not available. 12V DC operation is a separate setting.
just my experiences
