Used for the first time a couple of weeks ago on a trip to the Fl. Keys. Just a tip, you have to work out the spacing just right otherwise the hose will sag at a joint or two when you flush the tanks. Had to readjust the spacing several times when I dumped the tanks but next time will set up from the trailer first, then end at the drain. Also won't try to set up with the slide out (if your running under a slide). Crawling under to adjust was extremely uncomfortable.
