About

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, 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.

Today, Marx Trailer is owned and operated by me and my wife, Robin. In 2012 we moved into a brand new building on the corner of 3rd and Lewis Blvd, just one block South from our original 4th Street location. We have 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.
