Embodiments of the present invention provide a mobile target range trailer. The mobile target range trailer includes an extendible main body having telescopically intercoupled outer and inner sections, a hitching element coupled to the main body proximate a first end of the body, and a plurality of wheels coupled to the main body proximate a second end of the body. The outer and inner section of the main body cooperatively define an interior space. The main body is shiftable between a retracted position and an extended position to increase the maximum dimension of the interior space. Such a configuration enables the trailer to be transported in a retracted position and shifted to an extended position while stationary to provide an increased interior space for targeting.
