A forum search (white box to the left of your "Welcome" login info with FRF and Google radio buttons under it) resulted in over 50 times this question has been asked in one way or another over the years.
Here is one such thread. Gas to fridge while moving?
After reading it (and a few of the others) if you feel the topic needs to be "resurfaced" feel free to do so. If you need "tips" on how to search, our FAQs have some good ones. (I personally try to use no more than 2 key words and try a different combination if what I am after is not on the first two pages. I used "fridge moving" to find this one. "Fridge travel" and "propane travel" has tons more.
New members are still trying to get their problem fixed or figure out how to post their question. Once you have been around for a while, we kinda expect you to do your own research first before broaching a subject.
Do not take offense please,
I posted this not only for you, but for others as well.
