I do my pizzas on a stone or steel at high temperatures: 600º to 650º. Doesn't take long depending on the thickness and toppings..When I had my Traeger Lil Tex, I would cook the pies @ Max heat (~ 400º) on a pre heated rectangular stone. If I recall
correctly, it took 20 minutes or a bit less. In either case they turned out well; the cheese melted and just started to brown in places, and the crust baked just enough so it wasn't dry and crispy. It relates somewhat to cooking a steak. We have our preferences.
