When one does get a company to deliver gas, be sure to sign up for auto fill-up cause if you run out and need it filled it will cost you extra before they can fill it because the tank was completly emptied. If you are on auto fill-up the cost is theirs.
I have a 300 LB tank & have it filled right before bear season each year. I have yet to run out. Use it for heat(30K BTU wall heater) & cooking. All deepnds on size of camp & your use but for me once a year fill has been enuff..
