I bought this to have charcoal and LPG in one unit because I grill or smoke with both using smoker boxes. The thermostat in the charcoal side has never worked. The gas regulator died on the91st day of ownership causing me to buy another. Now the front castors on the unit have collapsed because the metal they are mounted in is too thin with no support. The rear castors are fine because they are in a structure that includes the rear legs. The two cooking areas affect each other making it very hard to control temperature while cooking. This my third and final Charbroil Grill.
