Gdetrailer, The only plastics wd40 says to avoid are polycarbonate and polystyrene ( mostly clear ). Don't think this includes sewer hoses.
In my case the tube dries before the hoses are inserted. I do not spray the hoses.
Been spraying my outboard motor, small engines, and all kinds of things that have plasic on them for years. Never had a problem with plastic melting away so not to worried.
I am more concerned about my sewer hose failing due to poor construction and crappy materials used in making it. Tossed the el cheapo that came with the TT and now feel pretty confident it won't blow, especially not spontaneously. :)
