Hi everybody,

So we purchased a 2009 Supernova 6400 back last Nov, only 40000 miles on her. We replaced/ fixed a few things but overall she is in great shape. Will be replacing roof this fall since a couple leaks have popped up after a lot of travel this summer.

BUT we discovered after our 3 week trip to Montana that the master bathroom sink drains in the rear black tank, NOT the Grey tank. The shower drains into Grey tank, though. Had to have been that way since factory I would think and never corrected. My question is, has anyone run across this issue , and if so, how hard of a fix was it. Ridiculous that the problem exists, but I want to get it fixed so I am not filling up my black more often than I should be. We boondocks a lot when on long trips and it was driving us nuts since we filled up that black tank so fast. And thought we had a clog in the Grey for the longest time��.

Any help/ suggestions/input would be great!!
