We are new owners of a 2012 Dutchman Grand Junction 340 RL. Our kitchen sink has gone from slow drain to no drain. I have poured bleach down the drain and run a snake (12 feet) to no avail. What should my next step be...
I am thinking you have two grey tanks, are you sure that both are drained. (Only asking this since you mentioned that it is new to you, I am not being rude.)
If you got the snake in 12 feet, I would think you made it to the tank, and the drain wouldn't be clogged.

I would agree with EricNSTL. After looking at the floor plan of the 340 RL I think you may have two gray tanks. Look for another drain handle just in front of your tires on the drain side.
