I am afraid that I cannot tell you the exact location of the drain on your particular RV. In some RVs there is a valve in the water compartment that allows you to drain your fresh water tank.
On other RVs the drain plugs or valves are located on the low point of the Fresh Water Tank itself. If you find that you have a plug in your fresh water holding tank and you want to make it easier to drain in the future you may want to install a Fresh Water Tank Drain Valve in place of the plug.
To get a better idea of where your drain valve could be located on your RV you may want to watch the video below by RV Expert Mark Polk from RV Education 101 which walks through the process of draining and sanitizing the fresh water tank on an RV.
