How to keep propane from freezing

I am in Klamath Falls, east of the cascades. The winters generally are not super cold. We get moderate snowfall. I'm just trying to wait out the winter so that come tax time I can go home. I realize that an RV is not an ideal place to winter in (to the ones to point that out). Understand I make around $1400 a month. I have two dogs that i WILL NOT part with. I have no family here and none of my friends are able to let my dogs stay. The everage cost of an apartment is $1200-$2400 a month with said dogs. I'm not trying to be rude, but I want to make it known I am not some idiot who chose to winter in an RV because it sounds like fun! I am trying my best to make a bad situation livable. If I had money to go home, I'd be gone. If I had money to rent a home, I'd be thrilled. I am a responsible person and pay my bills so I don't have anything left over, even for food. So I understand the sarcastic remarks being I am a newbie to all this, but that is why I am HERE. I know your knowledge can get me through this awful period of time and I need that knowledge right now. I appreciate everyone who gave me such awesome advice! I know it CAN be done as some on here and the internet have done so. I'm just trying to survive.
