I've been wanting to buy a regular-sized 18" Kamado ceramic grill, but they're extremely expensive. Not only that, but I don't live in the continental US so I have to pay to transport this 300-lb grill to my place by air.
Let's say that I buy some gasket for an airtight seal, a proper top vent, among a few other improvements, would this function as well as a Kamado Joe or any other ceramic Kamado?
With these minor improvements, would this produce even, steady heat? Would clay insulate as well as the ceramic dome of the BGE or the Kamado Joe? What about maintaining a precise temperature for several hours?
