Apparatus and associated methods relate to a modular vehicle roof frame with at least two support members having at an upper end at least one coupling member through which the support member is axially assembled and releasably coupled to a plurality of top frame members such that each top frame member is releasably coupled to a plurality of support members. In an illustrative example, when the frame is assembled the support members may be substantially vertical and the top frame members may be substantially horizontal. When the frame is coupled to a vehicle the coupling members may, for example, be oriented substantially parallel to a longitudinal axis of the vehicle. The frame may be assembled, for example, by alternately assembling top frame members and support members. Various embodiments may advantageously allow a disassembled frame to be stored within a small sized container suitable for various ground shipping services.
