Must I really have the coach deep cycle batteries?

My son has Walmart 12vdc marine batteries. Inexpensive, good warranty, maintenance free, and gets the job done.

Thanks for the good advice. No slideouuts and the fridge works on either 120 or propane. I'm just going to install a battery from my auto just to cover things. I'll double check the converter output voltage.

Just to be clear, the control circuitry in your fridge works on 12 volts and must have it or it will shut down the cooling system, whether it is on 110 or propane, if 12 volt power is interupted. So your solution is a good one. Even a momentary disruption of 12 volt will shut things down, and they may not start back up (or may) depending on the unit and where it was in the cycle and what power (110 or propane) was being used.

Someone else here may have better information here, but that is what I have experianced.
