Drain hose racks, a good thing?
It seems to me that blocking the drain hose so that it is in a perfectly straight line may not be a good idea. I'm sure that it may drain more efficiently, but, you are loosing the natural trap forme...

According to the pros the gentleman in the link above had to use, you should be leaving the grey valve open constantly or solid buildup will be a problem. Unlike the black tank, there is stuff that goes into the grey tank that needs to keep going and not sit on the bottom and solidify into a solid mess.
According to me however, do whatever has been working for you.
I actually think that the "pro" in the quotes above is contradictiong himself. I think it is the leaving of the grey valve open that created the layer of stuff in the tank. If the grey was allowed to fill and then be dumped, the material would have been flushed out before it formed the layer. But, either way will work for most people.
Also, each person should determine the plumbing system of their coach. In many coaches, the kitchen sink empies into the grey tank. In my coach, the kitchen sink empies into the black tank so the grease, food particles, etc. mentioned in the link above goes into the black tank where it belons. This system also adds more water to the black tank and less to the grey tank. It is a more balanced system than many coaches experience. I also periodically add an enzyme to both tanks (valves closed) when sitting for a while.
Neither of my tanks have a flush system and I have never had any problems. I keep my dishes and the kitchen clean, but the inside of the black tank is on its own. It looks good using a flashlight to look down into it when empty.
