As far as the panel, it does not completely enclose my tank. In the passenger side compartment 2nd from the back, the panel only blocks the top half. If you get down and then peer upwards in that compartment behind the panel you can see the end of the water tank. Does the panel serve to help keep the heat on top (warm air rises)? It might
, but not to a great extent IMHO.
My TS water tank drain valve is accessible in that same passenger side compartment on the tank fill/drain line. There is one pipe that comes into the bottom (passenger) side of my water tank, through that line the tank either fills or is sent to the water pump depending on the settings of the valves. Right near where that line enters my tank there is a "tee" and a drain valve with a nipple leading down so it can drain underneath. The valve handle itself is all that is visible inside that compartment and very easy to miss if you are unfamiliar. It is labeled "low point drain" on mine, but even the label is hard to find unless you are looking.
By the way it takes forever
to empty the tank via that drain if you have any quantity of water in the tank, if memory serves it is just a 1/2" PEX line. To speed things up I leave the drain closed so the pump can draw water from the tank and open the other drains which are on the pressure side of the water system. Then when the pump sucks air I open that valve to let the rest passively drain. But if time is no concern it will eventually empty just by opening the valve.
