Mine is an '05 so it is likely the same as yours.
If you are looking to drain the fresh water tank, the drain is in the compartment where the propane tank is. There are 2 drains there, one for the H2O tank and one for the coach water lines called the low point drain.
Just unscrew the end caps.
The hot water tank drains through the anode plug.
Hope this helps.
