Abstract
A utility trailer includes a base frame with wheels attached and a cap. The cap is moveable between a first position in which the bottom of the cap is in sealing engagement with the base frame, and a second position vertically displaced from the first position. In the first position, the cap forms a sealed enclosure for protecting contents loaded onto the base frame. In the second position, the cap is raised to facilitate loading and unloading of the contents as well as to permit access to loaded contents from substantially any location around the perimeter of the trailer.
