Marx Truck Trailer Sales was founded in 1965 by brothers Wally, Don and Bob Marx. At the time, Wally and Don were both working as factory salesmen for Trailmobile Corp ; Don in Milwaukee and Wally in Sioux City. What began as a local dealership for new Trailmobile semi-trailers soon grew into a regional dealership with 3 full service locations ( Sioux City, Sioux Falls, Des Moines ) and a parts store in Omaha. In time, the other stores were sold and we now operate from the one original Sioux City location, but in a very different form. Today our focus is on trailer parts and repairs, trailer rental, temporary portable storage, and new cargo trailers. We also sell used trailers, snowplows, truck bodies, truck parts, accessories, hitches, safety equipment, and on and on. Chances are if you need something related to transportation, we can help. Our parts delivery trucks are on the road every day, delivering maintenance parts in the tri-state area. Marx Trailer has built a tradition of servicing the trailer business with a knowledgeable and courteous staff. If you have done business with us before, we thank you. If not, we look forward to the opportunity. Dave Marx H. C.
