Surfside 32 Fresh Water Tank Drain

Trying to help out a friend with a new to her RV: 2007 National Surfside 32C.
We want to sanitize the fresh water tank, but I can't find the fresh water tank drain. My thoughts are to fill and drain a couple times, then treat it with a small amount of bleach and repeat.
No manuals, just can't find the fresh water drain valve.
Thanks for any help.

I'm a noob, but the valve isn't near or under where you fill the fresh water tank? Weird.

If all fails you could just let a faucet run to flush the tank and the pipes and water heater.

Here's a link that gives the steps my family always used to sanitize the system.

Again, a noob, but something is better than nothing. Good luck!

My 2006 Surf Side has the drain directly from the tank, which is in the first compartment back of the generator on the driver's side.

on my 2001 Surf Side the outdoor shower is the fresh water tank drain.
info from my manual...
System Draining Procedure: • Level the motorhome, side-to-side and front-to-rear. • Turn off the water pump and the water heater. • Open all fixture valves. Note: The system will drain through the outside showerhose. • Open the watertank drain valve. • Remove the drain plug in the water heater. • Operate the water pump for approxi mately 30 seconds to remove water between the tank and pump, then shut off. • Remove the Water Filter under the galley and drain. • Any water remaining in the system may be removed by attaching a blowout plug adapter to the fill connection and then blowing compressed air through the water lines.
