CyberDawg, I've never had a problem with my fire box or gasket after 2 years of extreeeem high temp searing. Like someone posted previously the grate temp can pass the 1200 mark (better than Ruth Chris!!) The gasket is just a normal wear and tear item that will need to be replaced over time. My 2 cents....new eggs should be broken in slowly. Before burping, put your beer down and open all vents. Get that egg as frickn! hot as possible to compete with a fr8tdog steak cheers
