Abstract: A tower system adapted to be secured non-permanently to different sized cargo portions of a moving vehicle is disclosed. The system comprises (i) a tower structure including means to allow a user to sit on the tower; and (ii) a support member to which the tower structure is secured, the support member including front and rear channel members to which the tower is releasably secured, each channel member having two end portions, each end portion of the channel members being in contiguous relation to a device that is slidable with regard to the channel members and adapted to be secured to the channel members, each device extending from a member that is structured to be force-fit and secured against the cargo frame of the vehicle in a non-permanent manner so as to lock the support member to the cargo frame.
