RMS courted heavy equipment suppliers and by 1960 took on statewide representation of Clark wheel loaders, Blaw Knox asphalt pavers and Link Belt cranes and excavators. The company entered the truck equipment business in 1972 and expanded that operation when it became the Midwest distributor for Telelect products and other lines of truck mounted equipment in the Dakotas, Minnesota and Iowa.
