I use their tank---500 gallons. Doesn't cost me a dime as long as I buy propane from that company. Sits in back yard--can not be seen unless you are behind the house.
I run hot water and heat on propane---so if the power goes out we still can take a hot shower and stay warm. We paid $1.37 per gal. this year.
Plus we still have a electric forced air furnace in the house. No NG out here.
