Happy camping to you, too!
I believe that petcock below the slide is the fresh water tank drain even though it is marked low point drain.
If you go back to where the water heater is and look under just below where the cable tv input is located, you will see two white pex lines poking through. If you go to the bathroom sink and reach your hand through the cut out section towards the floor, you should feel two mini gate valves. When you pull up on those, that drains the system thru those pex pipes below.
That seems to be how mine is set up anyway. Mine is a 2016 MRB
I also pulled the panels from below the fridge and that is where there water heater bypass is located and the panel below the kitchen sink...that is where the water pump is located and the valves and tube to suck in anti freeze when winterizing.
Hope that helps!
