Abstract
Abstract Disclosed is a wheeled trailer frame having an upper and lower deck. An auxiliary frame is adapted for attaching to the base of a conventional camper disclosure and carries wheels which are accommodated on ramp members detachably secured to the trailer frame. The camper can be moved onto the upper deck of the trailer from the side of the trailer, and a boat can be loaded, from the rear end of the trailer. The camper enclosure and boat can thus be loaded and unloaded independently of each other.
