Chuck’s Truck by Peggy Perry Anderson.
Perfect for toddler and preschool storytimes, this title combines two beloved subjects:  farm animals and trucks.  Chuck, a farmer, has an old beat-up truck.  By the time all of the animals decide they want to come along to town, the truck has broken down.  After the truck is towed back to the farm, the animals take care of the situation by calling in a mechanic.  Then they surprise Chuck with a shiny new truck.  The illustrations are deeply colored and very child friendly.  With its limited text but clear story, this is a perfect choice for storytimes for the very small.
