So, the rest of the story! The slide went all the way out today, with a little difficulty halfway. I am not surprised......
The water leak is on the braided metal hose connected to the faucet under the sink. Since parts are not sold for the kitchen sink faucet, I have to replace the whole faucet with part #315240-01-01A, according to the OEM Parts Coordinator at our local Camping World.
