Abstract: A loading device uses a hitch to support a boat trailer and boat in an elevated position on the rear of a camper. A first member attaches to the aft end of the boat trailer, a second member attaches to the rear of the camper, and latches on the first member engage dogs on the second member to pivotably couple the members together. A winch line is attached at one end to the fore end of the boat trailer and at an opposing end to a winch mounted on the camper. The winch can thus raise the fore end of the boat trailer and thereby rotate the boat trailer about a pivot point through the dogs from a pre-loading horizontal position on the ground to an elevated position supported on the rear of the camper. The loading device is thus mechanically simple because it only needs a hitch, a winch, and a winch line. It is also power efficient because it only pivots the boat trailer, rather than lifting it and then moving it laterally.
