The oven in this unit is a bit small for the really big events (lallapolozza, edgefest, roadside attraction etc) but very good for more of the commonity fairs and festivals. I used to be in the mobile catering business and if you want the BIG events you have to be able to push out a huge volume of food at a time. It looks like it would be easy to upgrade the oven if you were looking at the really big events but if not you should be fine. If I rember right they called themselves “express pIzza” it looks like the same truck I looked at (online) a few years ago.
