Two of Los Angeles’ most popular food trucks, The Grilled Cheese Truck and Coolhaus Truck, are teaming with Nissan to combine their takes on two food classics — grilled cheese sandwiches and ice cream sandwiches — with a pair of custom-outfitted Nissan NV vans.

The two NV2500 High Roof food truck concepts are making their debut this week not on the streets of L.A., but inside the Convention Center’s West Hall where they provided gourmet sandwiches.

The Nissan NV food truck concepts feature custom fold-out serving windows, work counters and full exterior graphics.

“Since its introduction last spring, the Nissan NV van is proving itself in a wide range of commercial uses, from construction to delivery services, in both standard roof and high roof body styles,” said Joe Castelli, VP/commercial vehicles and fleet, Nissan North America. “The Nissan NV High Roof model is especially adaptable for food truck and catering use thanks to its 76.9-inch tall interior, which provides the flexibility for the mobile chefs to comfortably move around inside while creating their gastronomical delights.”

The Nissan NV is offered in three well-equipped models: NV1500, NV2500 HD, NV3500 HD and with a choice of two powerful yet fuel-efficient engines: a 4.0-liter V6 and 5.6-liter V8. Both are mated to a standard 5-speed automatic transmission.
