Gold Nugget Manufacturing Inc. was a local company/farmer who built trailers. This is a nearly complete 1,000 bushel grain hopper trailer. Typical farmer build -- it is OVER built. Look at that channel iron the length of the trailer! Two fiberglass hoppers with three slide openings (only have one trap door) as well as fiberglass sides.
You could cut off the upright steel and make a solid flatbed trailer.
Tires: 11-22.5 on the front axle. No tires on the rear.
