We’re thinking about adding a full convection oven to the truck. We’d use it for warming food, and perhaps for baking in the morning when we add breakfast to the menu.
In NYC today we found a great option. The Moffat oven. Burns propane (hard to find and a must for us), is very energy efficient at 60,000 BTU (also important for us), takes full sheet pans, and even has steam if you need.
We’re going to try to track one down locally.
