Our first rv/motorhome and so many questions!!

In an accident, the excess flow device will stop any leak, and even puncturing the tank will not cause an explosion. LPG refrigerators are designed for use while driving; there is no reason to not use them as designed. You have a much greater risk of fire from the fuel (gasoline) system on your MH than from the LPG system. In fact, you have a better chance of getting hit by lightning than you do of having a fire in your RV because of running the fridge on LPG while driving.

I run my frig on propane when not on shore power. I also run my generator to provide AC in hot weather. My gen and furnace in cold weather my dash air and heat is basically useless.

There are some tunnels and such you must turn off propane prior to entering, they are marked.

Get a 12v crock pot and put your meal in it each day before driving it will be ready when you stop for the night.

You know most of us were born knowing all about RVing. :B

I keep reading that running the fridge on propane while driving is a no no but can the refer be run off the inverter while traveling?

You should shut it off for fueling and you will have to have the propane shut off at the tank for many tunnels and some other places. Many have been known to blow out while driving, but with most newer (last 20 years) this is not an issue.

We have a 12 cu ft Norcold and a 1000 watt pure sine inverter. If not, what can you do instead of the propane?

Yes, you can, but you have to monitor the house battery to be sure that the isolator is working properly and the charge is being maintained/

Also, we have a Magnum AGS stand alone system with a 5500 gas Onan generator. I think I understand how the AGS is supposed to work and have set the limit at 10.5 volts, but when we enable it, even though we know the batteries are at full charge, the generator comes right on and doesn't shut off. These are my 2 main concerns at this moment and will appreciate any insight from those with more experience.

There are at least two things wrong with the AGS.
The auto-start voltage should be way higher than that. At 10.5 a lead -acid battery has been damaged beyond recovery. That should be set way closer to 12.0 volts.
If the AGS trips when you have a fully charged house bank, it is defective. Get it repaired or find out what its voltage sensing issue really is.

Regardless of what has been written above, reefer fires are not that uncommon. This is one of the reasons that RV insurance is so high. The fires are almost always related to the lack of maintenance of the burner system. It can be just carbon accumulation (often blamed) but it is very often the result of nesting material deposited in the burner assembly by critters. Mice and birds can do this in a day, and either can get in through the tiniest of holes.

It takes a lot of electrical power to keep up with the small propane flame that runs an RV refrigerator. If you switch to electric and forget to switch back to flame, you will quickly drain your batteries. Plan on replacing them. Running down the batteries can reduce capacity and will greatly reduce life expectancy.

We are fulltiming, going on 14 years. I set our fridge on Auto and never worry about it. When hooked up to power or on the gennie, she's working off electric. Once we unlug and that power is no longer available, she switches over to gas. Easy peasy.

Does your auto gen start also have an option based upon the temperature? Ours has an option where the generator will start if
1 - the batteries are below a level we set
2 - the temperature is higher than we set
3 - the temperature is lower than we set.

2 & 3 were our primary for getting the auto gen start when we had pets. We wanted to be sure in case of a power loss in an rv park that the AC would start up to protect the pets. Maybe there is something similar on yours.

Ours also has a quiet time option where you can designate a range of time where the generator will not come on. That may apply to your situation because if you have the quiet time set to on, then the auto gen start will sometimes kick on ahead of those quiet hours to "prefill" the batteries.

I have two firemen in my neighborhood. Both long time Captains, one retired.
I asked them about fridge fires. In their many decades of combined service, neither of them had EVER seen an RV fire caused by a fridge. Not even one.
They had seen lots of them burn because by engine fires though.

not every one runs the frig on propane while traveling. the rv Dr and rv education guys say no do not travel with it on. it only takes one moment of forgetfulness and leave it running while getting fuel and blow up half the country side. and it does happen. I fought fires for 30 years and in those 30 years I fought many rv's with the frig going. our town has a nice new gas station from one motor home fire. a truck company CEO build a nice rv and he burned down on his maiden trip. it's your choice, just don't let your insurance lapse

I turn it on to auto when I de-winterize and leave it that way the entire season. It's designed and both UL and CSA approved to be used on the road.

The two schools of thought and a 3rd option

The AEON insurance school, which by the way I attended. (It is offered at many FMCA rallies)

Turn it off because in an accident there is a teeny tiney chance of a propane fueled fire. Ok, I will admit that is a danger... BUT

The other school.. The danger is not that great and if a propane line is breached there is an excess flow device that will limit or cut off propane flow.

My Theory
The biggest propane danger is what is called a Fridge Fire.. I check my mirrors often and if it catches fire .. I'm bailing fast and grabbing 25 pounds of powder on the way out.. (yup I have that) or a can of foam or both.

But imagine this.. I'm on my way to said FMCA rally.. Fridge fire on teh freeway.> The guy behind me in the multi million Prevost honks and hollers as he passes ON THE OTHER SIDE.. I look, pull off, My rig is history,, His, undamaged.

Ok, version 2

I turn off propane. Get to the rally and am parked next to said Multi-Million dollar Prevost.> Same fire.. by the time the FD gets there his, mine and likely one or two more are toast. I think my insurance agent would rather that did NOT happen.
