Abstract: A combination trailer and ramp assembly (20) is provided. The combination trailer and ramp assembly includes a trailer (24) having a floor assembly (30) including an upper surface, a lower surface, and a length. The trailer further includes first and second sidewalls (32) extending from the floor assembly, and a side door (34) located in at least one of the first and second sidewalls. The combination trailer and ramp assembly further includes a ramp assembly (26) slidably disposed on the lower surface of the trailer for reciprocating movements between a stowed position, where the ramp assembly is stowed underneath the floor assembly, and a deployed position, where the ramp assembly extends along an axis substantially parallel to the length of the floor assembly to permit access to the side door of the trailer.
