Hi Peggy, I skulk your forum a lot, and about a month or two ago you recommended a brand of hose, and as I recall your words were that it is a bit more expensive, but it was guaranteed to not let smell permeate for 10 or 20 years. I searched for that thread, but did not find it. Can you repeat that advice/hose brand? I am looking to replace the hose from my head to my holding tank this winter and want to get some of that. If there is a SBO link, that is even better. Thanks Ray
