Stoughton Trailers Brand Guidelines: A Wisconsin Family Firm Built From a Bankrupt Body Shop

An engineering graduate and a failed firm.

Stoughton Trailers began with a first job that went wrong. Don Wahlin graduated in mechanical engineering from the University of Wisconsin–Madison in 1960 and, the university’s College of Engineering wrote in November 2025, was hired that June by a small company in Stoughton, Wisconsin, to design truck bodies; by November it was bankrupt. Wahlin borrowed from family and friends, bought the remaining assets out of bankruptcy and, in 1961, founded the business. The trade magazine Trailer/Body Builders dated the start to April 1961 in a 2011 anniversary article and named the former employer as Stoughton Cab & Body; the company’s own history names it as Moe, Parley and Moe Corporation, and names Don and Carol Wahlin together as the founders.

The name changed as the product did. Wahlin first called the company Stoughton Truck Body. In the mid-1960s — 1965, by the company’s account — it became Stoughton Body Inc. and added truck trailers to its truck bodies, starting, Trailer/Body Builders reported, with a trailer for city delivery; flatbed trailers followed in 1964. As vans and platform trailers grew in popularity, the firm took its present name, Stoughton Trailers, in 1973.

Semi-trailer production started in a city-owned building on Academy Street, which the company calls Plant 1 and which now holds its corporate offices and engineering test facility. Trailer/Body Builders reported in 2021 that the early years included a fire in 1967.

Plant 1 to Plant 8.

The company tells its history through numbered plants. By its account, Plant 2 was built in 1973 for over-the-road vans and flatbed trailers; Plant 3 followed in 1981 and now houses the grain trailer line; Plant 6, the main assembly plant, opened in 1985 and was doubled in size in 1987; and Plant 5, built in 1993, fabricates and welds many of the components. That in-house fabrication, it says, is unusual in the trailer industry.

It also spread beyond the town. Plant 7 at Evansville, Wisconsin, added in 1993, builds intermodal containers and chassis and is the largest of the company’s plants. Trailer/Body Builders reported in December 2011 that Stoughton had reopened Evansville in March of that year, the last of the plants it had shut during the industry’s downturn, bringing back production of domestic containers and container chassis. Plant 4 at Brodhead began in 1994 as Stoughton Composites, a joint venture with the Aluminum Company of America, and became wholly owned by Stoughton in 1999, the company says. In 2022 it opened Plant 8 in Waco, Texas, its first plant outside Wisconsin, chosen, it says, for access to seaports, railyards and chassis customers in the southern United States.

The current range is short and practical: dry vans, refrigerated trailers, grain trailers and intermodal chassis, along with containers, all offered for rent, lease or purchase. In 2015 Trailer/Body Builders reported that Stoughton had taken on Barrett Trailers of Oklahoma City, a livestock trailer maker founded in 1973, and planned to add grain trailers to the Oklahoma plant. Around the factories sit service businesses that carry the same name: Stoughton Parts, Stoughton Trucking, Stoughton Logistics, Stoughton Lease and a financing arm, Stoughton Trailers Acceptance Corp.

Outside descriptions match that range. The university’s 2025 profile said the company makes trailers for over-the-road trucking as well as agricultural trailers and other specialty equipment, and quoted Wahlin on the metals involved: trailers, he said, are made of steel and aluminium.

Trailers and their makers.

Truck trailer makers sell a product that spends its working life on the road, and much of their imagery starts there: a long semi-trailer seen side-on on a motorway, a curtainsider rounding a bend, a tipper on a building site. The trailer is often the largest flat surface in a fleet, so the maker’s own name tends to sit small, on a plate, a mudguard or the front wall, while the customer’s livery fills the sides.

Bodies set the look of each category. Refrigerated box trailers are usually shown in plain white, with a cooling unit on the front wall, because the panels are built to be clean and easy to brand. Curtainsiders carry printed fleet colours on their sliding sides. Tippers are shown with their steel or aluminium bodies raised, and low-loaders with a heavy load chained down.

Factory photography is the second register. Makers show lines of bare chassis waiting for axles, paint and coating halls, sandwich panels being bonded and finished trailers parked in rows outside the plant. Product names tend to be short codes or coined words that sort ranges by body type, which helps fleets order the same specification year after year.

The third register is the trade fair and the dealer yard. IAA Transportation in Hanover and similar shows give makers a stand where new chassis, lighter bodies and telematics are lined up for fleets and the trade press. Dealers, rental firms and used-trailer centres then carry the brand into regional markets, where the customer is usually a haulier, a fleet manager or a logistics buyer rather than a member of the public.

A family firm that stayed private.

Stoughton Trailers has stayed in the family. Trailer/Body Builders, reporting in January 2021 on In Business magazine’s Lifetime Achievement Executive of the Year award to Don Wahlin, noted offers to buy the company over the years and a possible stock-market listing in 1999 that Wahlin called off. His son Bob Wahlin became president and chief executive in 2001, and the University of Wisconsin–Madison, which gave the founder its Distinguished Achievement Award in 2025, said the family’s third generation now works in the business, which it put at more than 1,000 employees.

Size is described differently by different voices. The company calls itself the fifth-largest trailer manufacturer in North America, with almost two million square feet of manufacturing space; the university’s 2025 profile called it the fourth-largest semi-trailer maker in North America and the largest durable goods manufacturer in Dane County. The company says more than 200,000 trailers built in its plants are on the roads of the United States and Canada, and it is building a new headquarters in Stoughton.

Its motto is “It’s in the Details,” and the company points to its rear underride guard, introduced in 2016, as an example. The Insurance Institute for Highway Safety said on 12 June 2025 that Stoughton’s 53-foot intermodal chassis was the first of its kind to qualify for the institute’s Toughguard award for rear underride protection, an award Stoughton had already earned for its dry vans and refrigerated vans.

For a design guide, Stoughton Trailers shows how a family manufacturer can carry its town’s name onto every trailer and every side business. Compare Wabash, another Midwestern trailer maker, and Great Dane, another American trailer maker. For this guide we use a highway navy, aluminium grey and a grain gold with a sans, an unofficial interpretation; no product or logo is reproduced.
