- SLO is a beautiful county. I run my two way on gas. When I had a three way, I used gas also. If you stop and forget to switch off the 12 volt...dead battery.
- Most run it on propane, some don't say its to dangerous. You could use the 12 volt dc but only when running the engine so your alternator is keeping up with the draw. It will kill and ruin your house batteries in a couple hours without aux juice. The 12 volt dc probably does the worst job of cooling your fridge. Propane first. AC second and in last place 12 volt dc. If its warm out and you don't run you propane fridge for 4 to 6 hours it would almost take a miracle to get it cold again after driving down the road for 6 hours with it off.
So to sum up. If you feel lucky run with the propane on. If you don't feel lucky run with the 12 volt. That's actually what its designed for. Just make sure to get if off 12 volt within a very short time of turning off your engine.
JMHO - Are you sure it's a 3 way?
A fridge big enough to be in a 2005, 38' RV would generally be too big to be a three way.
Put it in auto and let it do what it needs to. It's designed to run on propane going down the road and is UL and CSA approved to do so. - I've run my fridges on propane for over 25 years while traveling, never had a problem.
- I seriously doubt you have a 3 way. Put it on auto and go. I use to run my fridge on propane all the time when traveling. Now I have a residential and run it on the Converter, keeps it running when on the road.
Just a add on. You need 12V to power the circuit board at all times it is on. Don't be confused as it is actually powered by 110 or propane.
Bill - I would almost always run it on propane. Maybe at a long term stay with hookups switch to 120v. I would only use 12v if somehow the other two failed.
- From what I found, it has a 2 way, four door Norcold.
- run it on propane, it will work fine
you might want to turn it off for a few minutes when you stop to refuel
depends on where your fridge is compared to the fuel tank fill and the pump - propane
