Automatic electric to gas refer

[sarasafari]

I thought I read somewhere that you could buy a refer that automatically switches over from electric to gas when the 110 power shut off. Did I imagine this, or is there such a thing?

They are common. Almost all of the current production gas fridges will do this. Check the websites of Norcold and Dometic and their dealers.

All modern RV refigerators are automatic switchover types. They use 12VDC to power a circuit control board and use either 110VAC or propane gas to provide the coolong. Depending on the make and model you can select aotomatic mode which when 110VAC is available will use that and automatically switch to gas mode when shore power is disconnected. On some you can select electric only or gas only.
To use this type of fridge in a vintage A/S you must supply both 12VDC and 110VAC and propane gas to the fridge. The vintage unit will not have 12VDC at the fridge and will require adding 12VDC wiring to the rear of the fridge area.

I just put one (Dometic) in my 74 Argosy. This is the greatest thing ever! Not only does it detect which power souce available is the best to use, it will also ignite the gas without having to click on anything. It's like magic! I run some heavy gauge wire to the batery block, put in an inline fuse, and I'm ready to roll. I added a second battery to the unit, ran it on DC during the 4 hour tow, had it on propane for 3 days, along with the hot water heater and cooking. Used a small tank (BBQ size) of lp gas up over the 3 days, but didn't notice a dip in the electric charge.
