FW Drain Valve on Hemisphere 370BL

[larryi]

I've searched all of the threads on fresh water tank drains and can't find anything that resembles my 2018 Salem Hemisphere 370BL. The only thing I have found is three low point drains but no main drain pex valve or cap typically found. Did FR save money on this model and skip the main drain and only use the low point drains? Also, I have not found the overflow hose either so that is not an indicator. I'm wondering did the main drain get covered up by the underbelly covering??

Thanks
