Well we park for months at a time and can leave the grey tank open all of the time and not worry, so you really are talking about a way to leave the black tank open, correct? $200 - for that I can walk out and pull the lever once every two weeks (we have 80 gallon black tank) - since we are about the place anyway, a simple pull doesn't seem that hard. In fact, after 8 years on the road, I'm still trying to figure out why everyone has so much trouble with their tanks. We seldom look at the gauges - 10-12 days for the black tank, about 6 days for the grey when using the w/d and often just leave the grey open until the day before I dump the black tank.

I agree! That is basically what I did for the 5 years I lived full time in my motorhome.
If your system used standard electric valves to open and close via a timer, then it seems like it is doing what I did manually, but from a week long timer. I don't know that I would pay $200, mainly because I would need to reset the timer each time I Started staying more than a month in one location. Yet I would not want the dump valves to open while I am driving, the next time I removed the valve cap, and hook up my blue hose, I would not want a pint of black stuff from a open valve sitting there.
I do not find it that difficult to open the valves once or twice a month. Some will like the system.
I read one post many years ago, about a person asking for a combination hookup. Basically a one port thing, with sewer line, water line quick connect, and 50 amp plug that all fit into one cartridge, that mates up with a standard item built into the ground at the RV park.
I don't think that idea would have worked in part because I believe in separation of sewer and fresh water. . . Keeping the electricity away from water is something that others would want to avoid too! Even thought it was a "Good idea" - in reality it would not work at all.
Good luck with your idea! I have a plan to filter out the sun using a LED screen above the driver, but the development costs will be over $10,000! So that project stays in the drawer until I have a lot more money to develop the project!
