I have a 3-way fridge that I can set to automatic selector. Takes 240V, then 12V from vehicle, then gas. The 12V on-board battery only powers the device that makes the selection. It doesn't power the fridge cooling mechanism.
When travelling the fridge runs on 12V from the vehicle but 15 minutes after the vehicle is turned off, the gas is turned on - if it's available. Do people leave the gas on or is this a no-no?
The fridge reverts to 12V from the vehicle once the vehicle is running again.
It us unsafe to leave the LPG turned on while mobile Spyder. Alays best to turn of. It only takes a second to turn on if stopped for any long periods of time.

Must admit I have not heard of the system you describe, seems like more and more we no longer have to think for ourselves, however, absolutely big No No to travel with gas turned on, as Doug has said, consider the possibilities when refuelling.
When turned over to DC the fridge should run off the car's alternator whilst travelling, and should have a relay fitted to shut off the battery when the ignition is off, so you don't flatten the car battery when you stop for a couple of hours to go shopping. The fridge will stay cold for that short time, otherwise turn it over to gas while shopping, but make sure the gas is turned off and the fridge is back on DC before driving off.
Businesses like TJM and ARB are pretty full on with this sort of stuff, they will help you.

Good point Bevan. As a rule of thumb, gas should be turned off when travelling, except if in the USA where I believe they are allowed to travel with the fridge running on gas ( I stand corrected on this last point).
Thanks chaps. Just got a new van. The technology is just mind boggling compared to my old camper trailer. The camper trailer had a gas/240V fridge and could not be run on gas unless the trailer was actually wound up. My vehicle has a relay to cut the power when ignition is off. My gas bottle is actually locked in a front boot on the van. I was being lazy when I asked about leaving the gas on as I have to unlock the boot to turn the gas on when parked for any period during the day.
Bevan. FYI. The van has an OmegaLec control unit and the fridge is a Dometic RM2355.
That type of fridge is an AES model ,":Automatic energy selection" ,now available in a range of Dometic fridges
The Auto selection sequence is:
first see if 240V is available
if no 240 V check for 12V
If no 12V search for gas.
The safety recommendation is ALWAYS turn the gas" OFF" at the bottle when travelling.

I can only agree with what you have said PeterQ. We empty the lines as well, after turning the bottles off, by turning on a gas hob on the stove till it runs out. This should empty the lines of any flammable gas should a stone or such break a gas pipe.
Safe travels
