Grilling is sacred here in Texas, double that here in extreme south Texas. The first thing a man does after work is start the grill. The construction site has a grill. The factory has a grill out back. The car repair shop has a grill.
It is never gas. A gas grill is simply a kitchen stove moved outside.
It is always fired by wood. Mesquite here in south Texas. In other parts of Texas, maybe oak or pecan. Wood imparts the flavor. Propane has no flavor.
Use the propane orifice to fire up some beans or seasonally to fry turkey in peanut oil. Do not connect it to some sort of fancy-dancy stainless steel Home Depot BBQ box. Nothing edible can come from that.
Smokin' Joes in Oklahoma sells real grills. Or come down here to the border where old hot water and propane tanks are carefully cut in half, layed horizontal and turned into the same. My homemade grill came with rubber tires, a smoke stack, grates, two wooden shelves, and metal beer holders for $100. It does a brisket in short order that can be cut with a fork.
