Answer
To remove the Black tank, First, make sure it is EMPTY of all liquids, etc.  Remove the toilet, remove the floor flange, remove the dump valve assembly from outside.  you should be able to take the tank out from underneath after that.....

It is one of the least enjoyable jobs there is concerning any RV!
