I have a 1977 Eleganza II, floor plan 3. ...
<<snipped>>
... The only way I can see to drain the hot water tank is an outside nylon plug behind the gas valve.

My question is: has the hot water tank drained via the main water tank? Or do I need to remove the nylon plug on the outside, if it's what was described somewhere in this thread? ...

I am fairly sure your Eleganza (GMC upfitted) left the factory with an electric water heater mounted under the counter in the bathroom. They drained through a valve on the water heater and a tube into the wheel well.

BUT.. As you say there is a gas valve, and the PO had made changes, I am thinking you have a PO added propane water heater. It should drain from the outside.

Draining the main tank does not drain the hot water tank.

On GM fitted coaches like mine I have seen a plug or a valve like a radiator drain used. The location is dead center on the bottom of the hot water tank. I removed my valve and installed a small elbow and a ball valve. Then I connected a small hose that exits down into the wheel well using the OEM hole.

Emery was able to install the ball valve vertically (mine is horizontal) and make a straight run down to the wheel well. This is even nicer because he can open it up and if it does not drain he can stick a wire straight up through the valve and into the tank to open it up.

In my case I could not figure out exactly where to drill the hole in the wheel well so I used the offset OEM one. I open my ball valve and hit it with a very brief blast of air from inside the wheel well if necessary.

You do have compressed air available off of your suspension tank. Simply hook a tee and ball valve to the tank and you will have enough air to open up the drain and inflate tires. I do not think there is enough air to blow out the entire water system.
