The company is not an actual truck repair shop, as it is actually used to disguise the home of the Mole family. Apparently the so-called truck garage and their house is one and the same building, which is attached to a large, hidden motor, which can turn the house around, making the truck garage appear in the front yard, while the house is hidden in the back. A simple switch is what activates the motor, which can bring the house back to the front, and the truck shop in the back.
