Small Dometic frig with no freezer. Works great on Propane. Never used the 12v side. Is it wise to use 12 volts when traveling or using Campground power? Or whatever? Your observations are welcom. I think the converter is 15 Amps.

I believe this has been previously discussed on the forum. A search will reveal those threads.

I'd run 12v for two reasons. 1 to make sure it works and 2 to save propane

A Recent thread... http://www.rv.net/forum/index.cfm/fuseaction/thread/tid/25632703.cfm and contained within is a post that links to half dozen other threads on the subject of refer power source.
Actually theres another current thread on topic. Agree most every thing has been discussed before, but there is a wealth of information archived-searching previous threads may also yield more info/perspectives than the reponses recieved. I dont have a problem with it, some folks do.
That said sounds like refer doesnt have 110v option? only reason I can think of to not use 110 if shore power available. Couple of reasons off the top of my head to use the 110v if availalbe-110v works the best for cooling-propane second, 12v last. If using 12v on shore power thru converter-powere dumps in the middle of the night or while your away- youll come back to dead batteries.
AS for road use we have always used the 12v- most use propane. If using 12v on road you need to be diligent about turning off refer when engine not running. Pros & cons to either.

I have good knowlege of propane refers.
I also live off the grid and use propane refers at home and tt.
On the propane side functions of lp refers, a small flame used used in a heat tube to heat ammonia/water mixture causing the chemical expansion to create refrigeration.
On 12v or a/c power, a heating rod or element usually located outside of the tube that is either spot welded or rivoted to the tube.
It seems after years of electric use instead of gas, electrolisis sets in and damages the outer surface of the tube and diminishes or completely damages the heating element.
Since lp by design dissapates heat more evenly in the tube, a longer life expectancy.

The problem is in *telling* someone to search, not the actual searching itself. That would be just silly! Most every other forum on the 'net will attempt an auto-search of your question before you post it. Likewise business sites before you post an email. We don't get that here.

If "most every other forum" does a search for you, I must be a member of all the forums that do NOT. I belong to a dozen or so forums, and not a single one of them automatically searches to see if my question has been answered, before it allows me to post it. They all happily let me ask my dumb question even if it's been answered 1000 times.
Back to the original question:
IMHO 12V sucks too much juice. Trucks and campers are rarely wired well enough to power a fridge on 12V and keep the house battery charged. Usually if you run on 12V you will arrive at your campsite with a dead house battery if you travel very far.
On the other hand, the fridge uses VERY little propane. I powered my fridge for an entire summer's worth of camping, or about 14 days of 24/7 run time, on approximately 7 pounds of propane. That also includes hot water for showers every morning.
The fridge on propane is VERY efficient. The fridge on 12V is a pig.
