An extendable truck frame includes extended frame rails and interconnecting members. One end of the extended rails includes a connection that can be received by and secured into the back end of truck frame. In one embodiment, the extended rails can be positioned either at the general level of the truck frame to essentially extend the truck frame in the same general plane as the truck frame, but alternatively can be secured to the truck frame at a different, for example lower, position. The extended frame is releasable by interconnecting mechanisms so that extended frame can be selectively used.
