A trailer assembly for transporting recreational vehicles generally includes a base portion having a set of wheels, a holding assembly supported by the base portion and including a first support suitable for holding a first recreational vehicle and a second support adjacent the first support and suitable for holding a second recreational vehicle. The trailer assembly further includes a movement mechanism effective to move the first support and the second support from a launch position to a stow position. The launch position is a position which facilitates launching and loading of recreational vehicles with respect to the trailer assembly and the stow position is a position which is more space-saving than the launch position and facilitates loading of the full trailer assembly into a toy hauler or other limited cargo space.
