Here is your picture. I think I would run a garden type hose from the sink to the washout port of the tank (small opening up near the handle with a cap). When ready to dump it, just unscrew the hose, put the cap on the port, take to dump station and hook a regular dump hose from the tank (large port) to the dump hole.
Grey water can and often does smell just as bad or worse than the black tank. I would not run it on the ground unless camped alone in a large remote area. Your neighbors will not like you one bit if you run it on the ground. It is illegal, as far as I know, to do that in any state campground and most private ones. If you leave the caps on until ready to dump there should be no smell problem in the camper.

The dumping beside the neighbors is why I figured I'd just haul it back home after each trip and dispose of it at the house. It's only six gallons and I could empty it into a utility sink at home. I really don't expect to use six gallons on one of these trips. If it gets to that point, where I see six gallons isn't cutting it, I'll come up with a different solution. It's not like there will be 5-6 meals prepared each trip, etc... Just briefly washing hands and face, possibly.
I hadn't thought about draining to the small hole, but that would be an easier solution. I'll move in that direction. For now, I'll stick with it staying inside during use. I can give it some test runs in the coming weeks and see if smell becomes a problem.
Thanks to everyone for all the very fast feedback. This has been a fun project. I had a plan when I started, but have had to improvise a lot. I'll probably be posting another question soon about painting the outside.
