Black first and then the grey to flush out the hose. My rig has a separate 3" dump valve with fitting for each tank, so I rinse the black tank with quite a bit of fresh water and dump again a couple of times before disconnecting the sewer hose and moving it to the grey water.
I made a slick little adapter out of a short 1/2 inch pvc threaded nipple, a 1/2 to 3/4 threaded adapter, and a 3/4 pipe-to-male-hose adapter. I use this to connect the shower hose (after unscrewing the hand wand) to one of those toilet wands Camping World sells. With wifey on the inside running the wand off the pump and me running the dump valve outside, we can clean the blank tank pretty easily and quickly. Also, with this setup, you don't need to drag the nasty old rinse water hose from the dump station into your camper either. If anyone wants a picture of the adapter and wand let me know an I'll send ya one.
The black monitor lights quit working on mine after the 3rd or 4th camping trip. The sensors in the black tank get "something" on them that makes them quit sensing properly pretty quickly. This is a common well known problem if you read any of the RV newsgroups. Somebody makes a holding tank digestor chemical that keeps the sensors clean. It's no big deal on mine since the black tank is directly underneath the toilet and you can see the blackwater level when you flush. Eyeballing the level is much more accurate than those sensors anyway.
Black and grey water in the same tank? I'd hate to think any manufacturer would do something like that.
