Very very nice looking rig!! The grill on the right with expanded metal, is that gas??
The gas burner is on the left, 16" x 16" 55000 BTU gasser.
Are you're referring to the expanded metal? If so, the expanded metal is actually under the cutting board. When I use the gas burner and need to place something hot on the prep area, I remove the cutting board as the heat would melt it.
So, the cutting board is removable for those gas cooks when I need somewhere to place hot skillets, pots, etc.
