A floatable luggage carrier, for pickup trucks and snowmobiles, convertible into a camper and a trimaran, comprises a rectangular floatable main vessel. A rectangular floatable wing vessel is hinged along each of the longitudinal side walls of the main vessel, at the top. The wing vessels turn from a position side-by-side with the main vessel to an upside-down position over the main vessel: where the wing vessels side-by-side may define a trimaran and a camper, and in the upside-down position over the main vessel define a top for a luggage carrier, the luggage carrier being the main vessel, slidable into a loading platform of a pickup truck and usable with a snowmobile.
