Why do I have two petcocks drains on my freshwater, holding tank?

Hot water side - Cold water side of the plumbing system. Big tank drain should also be there - maybe looks like aone bug nut you take off with a wrench.

I think my trailer may be similar to yours. I have 2 brass petcocks that look similar to the drain on a car radiator. These are the low point drains for the hot and cold water lines on the street side. Close by is a white plastic (nylon?) spigot. The handle on it will pivot 180 degrees but as I recall is only open in the 90 degree position. This is the fresh water tank drain valve. On mine there is also a 4th valve near the 3 water heater bypass valves and looks just like them. This is the low point drain for the curbside of the trailer.

Wow, I have to quote myself here to explain. I ment to say "one big nut" not "aone bug nut" - actually, mine has a 4 sided brass threaded plumbing plug in my tank drain location. The PVC and valve hung too low and rubbed once getting into a parking space. It was at the center pivit point of my trailer. I was told by a dealer the PVC valve was an owner add on - not from AS - but I have seen them on several trailers like mine.

By golly, Yank, I believe you are correctomundo.
I now recall, that is how my 2000 was configured.
Now, I just have to find the white, plastic spigot.

Pics are my favorite. The low point drains look like they are coming out the bottom of the FW tank and is easy to understand why you thought that. On mine, the FW drain is one the side dead center between the tires. As Clancy suggested, you may have a simple plug instead of a spigot. See if you can find the other low point drain I mentioned above. It would be easy to overlook if you didn't know it was there. In this photo it is the one one the bottom right.

My petcock broke off during my trip to Alaska. I don't know whether it's all the rocks that I drove over or from a piece of re-tread that I hit on my way out of Atlanta. In any event, the guys in the Jayco caravan plugged it for me and it held pretty well. My Airstream is now at Jackson Center being repaired for some exterior damage and some warranty issues. Three months on the road and I am well-versed on my Airstream. Those weekend trips just didn't do it.
