You can buy a one inch hose for outdoor water landscaping pond pumps at Home Depot or Lowes for about 20 bucks. It is twenty feet long and you can shorten it if you want to match the length of the original hose. Now, it is not the quality of the Sanicon hose (which I now have in my C) but I replaced the one on our Roadtrek with the HD/Lowes hose and it had worked great for over three years when I sold the RT. Incidentally, I cut the hose down to the length of the original RT hose and it made almost two hoses, one to spare. So, really, two for twenty bucks. All I know is that it worked great for us. I carried the spare hose coiled up in the cover of the continental kit spare tire.
