An apparatus is convertible between a pontoon, a camper, and a trailer. The apparatus includes a main frame with longitudinally-extending beams and transverse beams. A retractable wheel frame supporting a double pair of wheels is pivoted to the main frame and is configured to swingingly retract into a center area of the main frame. Side, front and rear pontoons are attached to the main frame, with the side pontoons being extendable laterally to provide increased width to the apparatus. A vertical upright beam is slidably attached to the main frame, and includes a bottom hitch and a top boom, both of which are moved by an actuator attached to the upright beam.

1. An apparatus comprising:a main frame with opposing sides, a front, a rear, and a center area, the main frame including longitudinally-extending beams on right and left sides of the center area and transverse beams supported by the longitudinally-extending beams; a retractable wheel frame including wheels, axles, and subframe members, the subframe members supporting the axles and being vertically movably connected to the main frame; and pontoons operably supported on the opposing sides by the transverse beams for movement between an outwardly-expanded position where the center area is open for receiving the wheel frame, and an inwardly-contracted position where the center area is not sufficiently open to receive the wheel frame.
