I just had a 120 gallon propane tank delivered. Unfortunately they didn’t notify me when they were coming and hooked it up and left. I opened the valve and thought I was good to go. Well I came home tonight and my small tank on the other side of the trailer must of ran out of propane and it didn’t switch to the the new one. Well needless to say at 2am when I got home it was 34 degrees outside and 40 inside my 5th wheel. I plugged in my portable heater and bundled up for the night. Help! What am I doing wrong? I shut off the small tank and still nothing. I am new to this full time RV living and going a little bonkers! I have a 2007 Thor Jazz 5th wheel
Thanks!
