Ameritrail GN16-20

The register lists 3 versions with kerb weights from 2,150 to 2,950 kg, gross weights from 5,500 to 7,250 kg, lengths from 7,720 to 11,010 mm and widths from 2,180 to 2,550 mm. The range spans from a more compact to a very long gooseneck trailer.

With gross weights from 5,500 to 7,250 kg, the range falls into EU trailer category O3, for which a plain overrun brake is no longer permitted above 3,500 kg; gooseneck trailers of this size therefore usually carry a hydraulic or electro-hydraulic brake system controlled from the tow vehicle. The hitch mounted over the tow vehicle's rear axle transfers part of the trailer's load directly onto its bed, which, compared with a ball hitch carrying nose weight at the vehicle's rear, gives a more even axle-load distribution and improves stability with long or heavy loads.

Gooseneck trailers of this size carry larger boats, construction machinery or vehicles and, through the hitch positioned over the rear axle, offer better weight distribution and manoeuvrability than classic ball-hitch trailers. This body style is mainly established in the USA and Canada.

When buying used, check the condition of the frame and gooseneck coupling, the operation of the brakes, the condition of axles and tyres, and, on boat trailers, corrosion of the frame and rollers from saltwater exposure. Parts for axles, brakes and the coupling are available through the North American trailer trade.
