The sons of Roger Gust, who owned Twin Grove Trailers, started the business RC & G Square LLC that is conducting business as Twin Grove Trailers. Curt and Randy Gust worked for Twin Grove Manufacturing which started in 1976. Curt Gust has continued working for Twin Grove after he completed school. They built stock, feeder, and utility trailers for H&S. Along with manufacturing, they also sold Hillsboro trailers. In 1984, Twin Grove Manufacturing got out of the manufacturing business and became Twin Grove Trailers (TGT). TGT sold many different brands of trailers, but came across the best line of trailers, Corn Pro. In 2010, Curt and Randy Gust started their own business RC & G Square LLC continuing their many years of experience in the trailer business and taking over the business their father started.

We offer fast delivery of products via normal UPS ground because our supplier has 20 warehouses across the United States.
