If you have an RV refig it is 12V so the invertor is not even in the formula. Invertors turn 12v into 120v, convertors turn 120v into 12v, alternators are turned by the engine running and produce 12v. If you have an rv refig you need to have 12v for the controls, + a method to heat the ammonia. Either propane or 120v. If you do have a rv refig it is doubtful that it is connected to an invertor. Why add complexity and expense to an already confusing and costly system when you already have propane and a battery? No matter what you read on the net driving with propane on is not a problem, otherwise they would not have designed them to work while doing so. Unless of course you can show me a first hand experience of someone having an emergency while doing so. Yes, I do know that A FEW tunnels require the tanks to be shut off. So do ferry boats.
