More problems! I just tried the connection on my Roadtrek and even though I sprayed both the sewer hose and the SS with WD40, I could hardly get it on. Getting it off was almost impossible and the whole "end" of the hose came off with it! I could then disconnect the stinky slinky, but now I'm not sure it's "waterproof" after shoving it back on the sewer hose. This hose was replaced a couple of years ago at the dealership - could they have used an end that was just a little too large? It is held on with a clamp. Could I get a slightly smaller end on the sewer hose that would fit correctly to the Sewer Solution? I could take the camper back to the dealership if so. Anyone else have this problem?
