Answer:
Truck wholesalers.
Explanation:
Truck wholesalers, also known as jobbers, are simply trucks that are filled with different goods, usually semiperishables as explained in the question (fruits, vegetables, snacks, some types of grains).
These truck wholesalers or jobbers cover a specific geographic area, either looking for customers, or delivering to pre-set locations, especially small convenience stores and pop and mom stores, and hotels as well.
