The Saga of the Faucet:
The one thing that did not work on our Aliner when we bought it was the sink faucet. This was not a huge issue as we have a nice 2 gallon carboy, with a spigot on it, that we sit on top of the air conditioner and which serves us just fine. However, an operational sink would be way better. Our 5 year old grandson was greatly put out that there was a non functional part of the camper!
I took the faucet apart and found that the rubber plunger washer was just too worn to lift water up the line. No problem, right? I'll just replace it. Not so easy! I searched everywhere for one, but to no avail. I called Aliner direct, called all sorts of dealers, and the best I could find was a replacement for $75 + S&H !!!  After almost a year of this carry on we went to Hushard's RV Center. They fitted a new faucet for under $60, They also re sealed the read dome window that had been a serious leak problem.
