How much does a 30# propan tank weigh when full?

[snowball]

it might be that rules and or regulations are different because I have asked them to leave the tank in
the back of the truck but they wouldn't although they usually help load it. I have a 5th wheel last fall/winter while in the
trailer in Ogden Ut before moving in with daughter I went through a tank about every other day...it was cold and I still wasn't
successful in not letting it freeze...had I thought about it would have gone and bought a electric heater but just didn't so used to
heating with the fireplace that I didn't give it a thought...and it runs off of a propane tank
It's something one does you just get used to it or adjust
