A trailer having a main deck portion having a main deck surface, an upper deck portion having an upper deck surface, a connecting frame assembly, a plurality of rollers elements, and a tailgate. The connecting frame assembly can couple together the main deck portion and the upper deck portion. The roller elements can be arranged in one or more rows and can be mounted in the main deck surface or the upper deck surface so as to cover a substantial portion of the main deck surface or the upper deck surface. The tailgate can be coupled to the main deck portion and can be movable between a closed position and an open position.

A system and method of converting a wheelchair ramp system from one of a manual mode or a power mode to the other of a manual mode or a power mode. The wheelchair ramp system includes a bimodal bracket having a common spindle aperture, a common ramp, a common ramp fold arm, and a common fold arm collar. The bimodal bracket supports either a spring for the manual mode or a motor for the power mode. The common spindle aperture accepts a spindle of the spring or a spindle of the motor, each of which is captured by the common fold arm collar. The common ramp fold arm is coupled to the common fold arm collar and to the common ramp. A common stow switch is fixed to a bracket and a position of the bracket is used in both the manual mode and the power mode to adjust a stow position of the ramp.
