Yes, it is a Bimbo truck. Nope, no bimbos for sale but bread, bakery.
This mexican company is one of the largest in the world having operations basically, all over the world. It owns brands such as (you probably have heard about these): Entenmann’s, Francisco, Mrs. Baird’s, Oroweat, Sara Lee…. you name it. (http://bimbobakeriesusa.com/our_brands/)
Where the name came from? It’s a teddy bear’s name. That’s it.
