Marx Truck Trailer Sales was founded in 1965 by my father, Wally Marx, and his brothers Don and Bob. At that time, Dad and Uncle Don (Jack) 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. Over time, the other stores were sold and we now operate from a single Sioux City location, but in a very different form. Now 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.

Sioux Falls Winpump offers a wide range of high quality equipment and parts. We source the industry's top products at competitive prices so you can get what you need when you need it, to get the job done right.
