We're a dealer for both United Trailers and Haul About trailers out of Indiana and we can order you any trailer in their product line, including custom built trailers made specifically for your needs.
United also offers "package" trailers that are very common in the racing industry and a great way to get your car to the track. Please see the "United Package Trailers" page for more information on those.
United Trailers are very well built, top of the line trailers that will provide years of great service and excellent resale value should you ever decide you need something bigger or to retire from racing.
Here are some sample photos from a recent visit to United. As you can see, they offer excellent products and can build any enclosed trailer you might want.
