Hanna Trailer Supply stocks several 7-foot MTI steel cargo trailers, ranging from 12-foot-long to 16-foot-long models. Our MTI trailers come in a variety of colors and include side doors and slide-out ramps for easy cargo access. We typically order these trailers in with basic features, but we have the ability to order them in with any options that you may need. The most popular upgrades that we see customers order are a radial tire upgrade, 16” on center side walls and floor members and a slant top wedge nose. Radial tires last longer than bias ply tires and they perform better at highway speeds. The slant top wedge nose makes the trailer more aerodynamic and helps cut down on fuel consumption.
