The cost is high for the initial purchase and the fuel.
Exactly what oldjeep said. If you take the same money a truck costs and purchase a car you can have one hell of a car.
If you are going to open your own restaurant, then money will matter. Honestly? I'd buy a mini-van. Less expensive, more practical use, better mileage, etc. etc. I rented a town-n-country for a business trip and it was great. Comfortable, easy to drive, good mileage, plenty of room, etc.
