A wood-fired oven takes about forty minutes to come up to temperature and then holds it, so the working day starts well before the queue does. Once hot it will turn out sixty to ninety pizzas an hour, which means the ceiling is hands at the pass rather than the fire. Evenings and weekend events are where the trailer earns, because that is where a queue holds for two hours; a weekday lunch spot rarely fills it.
The trailer is built around the oven and around what the menu needs beside it — dough fridge, prep bench, cold for the toppings, extraction over the fire. What no build can decide for you is how much dough to prove the day before, and a sold-out evening is almost always a prep problem rather than an oven one. Cheese is the input to watch, close to half the portion cost, so a 20% rise takes roughly $0.30 off every margin above. Gas and wood, the site, insurance, running the tow vehicle, servicing and waste make up the monthly figure.
We price the 5 m trailer, oven built in, at $7 800. The portion is dough, sauce, cheese and toppings at wholesale plus the box. The sales-a-day column is not a forecast. Those three volumes are there to read the economics at, and which one you reach depends on the site rather than on the oven.
