Location of fresh water tank drain???

[dirtman]

We recently purchased a 1975 Trade Wind Land Yacht and the owners manual states that there are 3 drains under the galley. I can only find the drains for the hot and cold water lines. I cannot find a main valve for the fresh water tank nor do I see a separate drain line for the tank. I'd appreciate any advice on where the heck the drain valve and line are located. Thanks.

It's down there, but you have to do an ostrich impersonation to see it. If you are winterizing there are also low point drains in the rear of the trailer.
