I have a 2002 Journey DL kitchen slide, your sister coach. I had a leak last year. The flex hose that Winney used on my coach was so stiff it cracked the fitting that screws into the pipe that drains into the tank. I went to Home Depot and got a flexable hose and the plastic pipe fittings to make my repair. Been a year and all is well.
