What they have managed to do is to modify the interior of the vehicle. This was done by removing the passenger seats at the back and replaced with a power system that is powered by a couple of truck batteries. This will power both the refrigerator and food warmer in the back of the vehicle.

Keeping to Austin’s health codes, the awning does not actually touch the group at any moment. Throw in a canopy and they’re good to go for taking orders.
So far their project has been rather successful, allowing them to sell 50 sandwiches from the car in two hours. With their success in Austin, both the students are planning to add three more similar vehicles come January of 2012 but no word if they plan on rolling this franchise out to the rest of the country.
