Dough is no problem. I've been making pizzas for over 50 years since working in a pizzeria in high school.
I make all my pizzas totally from scratch including the dough and sauce. In a pinch and you need dough fast, Trader Joe's sells a fresh unfrozen dough that is pretty good. It seems most supermarkets sell a frozen dough that takes a day to thaw properly in the refrigerator. They would be options since making your own dough needs a lot of space a B doesn't have. I can't tolerate those pre made Bobolino crusts they sell in supermarkets. I do make up my own dough balls and freeze them. I have that figured out. In my previous B I never had the freezer space to make them up ahead of time and take them with me on trips. I will now.
In my previous post I already have the electrical use of the Breville figured out and it will be no problem in our B in a boondocking situation.
The PizzaQue is going to easily fit in the storage area in the back of our B. I haven't decided if it is good enough yet as I am seeking very high Neapolitan style heat of well over 700F. 900F is the ideal and my goal is to master the Neapolitan style pizza and ideally that is in a wood-fired oven.
A lot of people are buying Blackstone propane ovens
for high heat but they will not fit in a B in any practical manner. The guys in the Pizzamaking.com forum love it. So, if I buy a Blackstone or build a wood-fired oven I doubt I would also buy a PizzaQue as the Breville will satisfy my needs. Decisions...decisions.
