Black water tank brace

[popup2012]

I have a 2016  16 TBS with 4 wheels.  When looking under the TT I saw there were only 2 braces on the black water tank. I am assuming it is the black water tank as it is the last tank.  There was a brace  on the door side and one in the middle. Next to the drains the was no brace. Am I missing a brace ??

If you really only have 2 straps, you are missing one. However, I'll bet you have 3. The strap nearest the drain is hidden higher up in a "L" formed in the tank to make room for the drain outlet. Look all the way up over the drain.
