The 5th wheel assembly is ready for mounting. The sealed enclosure shown will have an air outlet added somewhere. The brush area will have an air inlet duct added. This way I can blow forced air through the motor and run it hotter. The pully shaft and motor face will have water proof seals, as well as the shield/air duct area. The pulleys will get wet, and the housing will vent/drain at the bottom. The pivot will be at the bottom so the dual air cylinders can have a long lever arm to get maximum downforce in the limited area available.
