Not familiar with the PVC type petcock on A/S, but on the pool at my old house, I used to use baby oil on the PVC valves for the solar panels. Worked like a charm.
Yea mine is a bear also. The problem is getting it started since the little tab sits against a flat surface. There is no easy way to get your finger behind the tab. Sometime a small screwdriver just to pry the tab away far enough is all you need to do. Once you get your finger behind the tab you can apply the force necessary to open it up. I haven't had to take the lubrication route at this point.

On the '03s (at least the Bambi), those type valves are gone. They use a smaller version of the valve that connects to a house toilet, except these move very, very smoothly. No binding at all.

Mine has a PVC ball valve. There is an elbow and the ball valve hangs right under the tank woth a big handle. Very easy to operate, but I worry sometimes about it hanging so low.

I'm sorry I didn't describe the problem clearly enough. The petcock I'm talking about is the one under the trailer to drain the fresh water tank for winterizing etc.
Sorry,

After many painful fingers, different lubricants, and extensions to increase torque, I had AS replace it when we were last in JC - works pretty smoothly now.
