A land drilling rig and associated methods are described that facilitate fast rig up of the drilling rig for drilling a well. In some embodiments, the drilling rig may include a rear trunk, a center trunk, and an alignment frame. The alignment frame may be coupled to an edge of the rear trunk and to an edge of the center trunk during unloading of one of the rear trunk and the center trunk from a trailer to align them during unloading. The drilling rig may be formed form a plurality of components, some of which may be dual purpose structures that store equipment during transit, testing, and rig up and that form a part of the support structure of the drilling rig. Further, base boxes may include moveable feet that can be controlled to walk the base boxes and the drilling rig to a selected location.
