I like to add the deodorizer with the breakdown treatment, it leaves a nice smell unlike what you put down the black tank.
I prefer to use a home made wand to clean out the "stuff" out of the black tank while the wife is inside the unit with the wand and I am checking out the "mess" with a clear 90 angle off the sewer pipe.
I bought the Rhino sewer hose which came with the screw type fitting which most places have, I later have bought a donut, but rarely used it.
I also bought the brass water pressure, seemed to be a lot sturdier than the plastic ones, but just my two cents. I also bought a one way value drainer, once I turn off the water, it drains itself....saving me a step to drain the water to relieve the water pressure.
