GSX - The GSX is our entry level flatbed gooseneck. It starts at 14,000 lb GVWR with 2-7K Dexter electric brake axles and can be upgraded to 21,000 lb GVWR with the right axles and frame options. It is also available with a pintle hook front end instead of the gooseneck. The most popular setup is a 20' deck with a 5' dovetail which would be our 25' model. This trailer is most often used in farming applications to haul things such as smaller tractors or hay.
