Abstract
A trailer for hauling on the fifth wheel of a tractor-truck. The fifth wheel attachment point of the trailer is substantially above the flat floor thereof, the trailer's front wall and floor being at right angles to each other as are the trailer's top and rear, but the angle between the rear and the floor being obtuse so that the trailer is taller at its front than it is at the rear. Jacks are provided at the front of the trailer to level the floor for loading while allowing the forward portion to be tilted downwardly for attachment to the fifth wheel and hauling.
