Unless an LP system can be retrofitted for a 5 gal. or larger tank, I would never even consider 1 lb. systems. You probably could not even get a full night from a 1 lb. heating unit. One lb. canisters are not re-filled.

The reason it's so hard to lose weight when you get up in age is because your body and your fat have become good friends.
