Ever since purchasing my Wildwood TT I have wanted to install an external Black Tank Flush System such as the "Toronado" or "Quickie Flush". I have found that given the way my Black Tank is mounted, only the bottom 3 inches or so of it are exposed due to trailer steel beam framing.. The end with discharge is fully exposed though.. The instructions say to mount the flusher on the opposite end from the the tank discharge and in the upper section of the tank sidewall.. can't be done.. Now I am looking at alternatives.. Has anyone use the Hydro King Flush that attaches to the discharge connection?? Does it work??? I have a wand type but do not like dragging a hose through the trailer to the bathroom... .. Ideas??
