In addition to its standard full-width mechanical gooseneck, Trail King’s Commercial MG-HG detachable-gooseneck trailer can accommodate four additional, interchangeable gooseneck styles, available in either full-width or narrow-width configurations with mechanical or hydraulic actuation. Lightweight options include aluminum I-beam or box-beam cross members, outer rails, decking, and front and rear channels. Designing structures to minimize moisture-trapping areas and priming and painting the entire trailer before decking or hydraulic/electrical/air lines are installed enhances corrosion resistance, says the company.
