Abstract: An accessory rack system comprising a frame rail adapted to couple to a side wall of a cargo area and at least one post engageable with the frame rail. The frame rail comprises one or more frame rail locking features and a tonneau cover support portion adapted for supporting a tonneau cover over the cargo area. The at least one post comprises one or more post locking features extending from an end of the at least one post. One of the post locking features rotates into locking engagement with one of the frame rail locking features so that the at least one post is prevented from disengaging from the frame rail and/or prevented from longitudinal translation along the frame rail.

Abstract: A drain system for transporting waste from a vehicle to a discharge location located spaced from the vehicle may include first, second and third modular components. The first modular component may be adapted to coupling to the vehicle and may define a first male connection. The second modular component may include a waste transfer portion extending between a first end and a second end. The first end may define a first female connection and the second end may define a second male connection. The third modular component may include an angled central portion, a first end and a second end. The first end may define a second female connection. The second end may define a waste discharge end. The drain system may further include a fourth modular component defining a first end having an opening for receiving the waste discharge end of the third modular component and a second end for interfacing with a tubular intake of the discharge location.

Abstract: A self-contained sanitary system includes a stand alone bench carrying a toilet with a flush tank for storing a source of flush water. The system further includes a holding tank. The holding tank is removably associated with the toilet and includes a pair of wheels and a retractable handle.
