When I saw this, my knee-jerk reaction was EH2 for shielded fire. However, I was on a job site and had a 1:15 ride back to think about it.
Most automobiles are enclosed and any fire started inside would be “shielded”. But a parking garage has been OH1 for a long time (although that may be reassessed). Also, the examples in NFPA 13 of shielded occupancies are very large (Modular houses). Where is the cut off between what OH1 would protect and EH2 be necessary? Who knows? A pick up truck has a lot less shielded space that an SUV. It is most likely a function of the size of the shielded area but how do you regulate that? Most food trucks are little more than delivery vans with kitchens and a side window. If 6 regular delivery vans were parked there, how would you protect it? I would lean toward EH2 because of the combination of the shielded space and the kitchen inside. To Ron’s point, there are a lot of other health and safety regulations (commercial kitchen without adequate ventilation, etc) that make this whole occupancy sketchy to begin with.
