Winnebago Dropping Truck Business: Winnebago Industries said it is ditching its money-losing commercial van business to concentrate on its mainstay, motor homes. The Des Moines-based builder of recreational vehicles began making delivery trucks early last year, but the line never caught on. Winnebago spokesman Robert Cooley said that business is for sale, but there is no potential buyer yet. The company has posted losses for eight consecutive quarters, but in the quarter ended June 1, losses were narrowed to $2.25 million from $4.03 million a year earlier.
