The Camp Chef is the way to go. It has 60,00 Btu vs that other one at 64 but the lava rocks put out more heat than the ceramic logs.
Mtn goat was the first on this. He had the napoleon. While it looks the most realistic it's not as hot
The camp chef is the best bet and a extra bag of lava rocks to pile on it so it's more of a dome or mtn. The more rocks will keep the heat more than a flame will. If you mod it your going to burn more propane. IIRC we get half a tank a night on a standard camp chef. I can't remember how many hours 4 ish..
