Thanks everyone for the input. It’s pretty much how I use my BGE right now. In fact, the last couple most recent dogs and burgers cooks I did on the BGE, and it definitely lights and gets to temperature faster than the Weber. I love both cookers, but it would be nice to replace them with one, and regain all that deck space. Current setup:
The KK would go where the Weber is, under the umbrella. I think Autumn Gold In pebble finish would look really nice there. Then the BGE goes away, the fridge moves to where the cooler is... it all makes sense.
I’m going to take @billg71’s advice, and have the Building Inspector check my deck to see if it will support the 550lbs, give or take, of a 21” with shelves etc. That, and if I can get the box up the steps!
