Best move I ever made - natural gas line under deck, natural gas grille. Never have to worry about the tank going empty. When the grille is stored inside, no gas.
I have a Phoenix brand propane grille. Instead of using tanks, I hooked up a 10' hose w/quick connect & ran a line through the basement wall w/ quarter-turn valve (LP fired hot water heat & water heater). Roll the grille over snap the hose on, turn the gas on & grille. No more having to fill tanks frequently! ~~ grnspot
