DOUBLE "M" TRAILERS has been selling Dump Trailers since before they were even popular. We built one for Our farm so we could haul off the Horse manure and take it to the farm fields and mix in with the soil. That was Hundreds of Trailers ago. We work with several companies so we can pretty much Custom build the trailer that you want. We stock all the popular sizes at Our yard. Feel free to give us a call day or night !
