3 way fridge
we have a 2005 itasca sunrise 38j class A. when we are driving 4-6 hrs should we put the fridge on aux,ac,or propane? should we run it off battery,or run the generator while drivjing, or have the propane on while driving? confused.

- Run it one propane. That's how it's designed to work. It will cool better on propane anyway.

My 1997 Class B has a 3 way Dometic fridge. It does not have an auto setting. I drive with it on 12 volt. It can't run on 12 volt with the engine off, therefore no battery drain. I switch to propane when stopped. I don't like having the main valve open on the propane tank because if I got in an accident the lines would have free flowing gas to explode. If you don't get in accident nor stop to refuel you'll be OK.
Your Asme and DOT LP tanks have EXCESS FLOW VALVES. IF you have a major break in the LP system the tank flow shuts OFF. Whenever I hear people state concerns about the worry you have, I ask them to dig up any stories of a LP assisted catastrophe with an RV. They never can, just "things they have heard" Doug
I did not know that. Thank you DOug for that info.steveh27 wrote:

- We've been fulltiming for going on 13 years, RVing for 40+ years. We leave ours on Auto all the time. When we travel, it switches to propane, when we plug in, it uses electric. Never had a problem.
Dale - propane
- 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 - From what I found, it has a 2 way, four door Norcold.
- 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.
