Has anyone added a gray tank to a non gray tank coach? Now i know it will be next to impossible for the dry bath side as the shower is direct to black
tank but what about for the kitchen sink and maybe bathroom sink?

In the 23' we have a Urine-diverting dry toilet installed
https://www.separett.com/en-us/our-products/toilets/urine-diverting-composting-toilets/urine-diverting-toilet-weekend-7010

Only the fluids go into the GMC tank, which, in my book, means, the
black tank basically became a grey tank. Not sure how the regulation
sees it, but that's how I see it.

But we are happy with the result.

I have a 1977 26’ Palm Beach that I have added a grey tank. The tank is located in the small bay in front of the forward fuel tank and behind the
exhaust “Y” connection. The tank only services the kitchen sink, I plumbed valves so that the kitchen sink can drain either into the Grey tank or
the black tank. The tank is 18 gallons and can be discharged via the same macerator as the black tank.

I am seriously considering doing it a little differently, namely adding a 19 gal black tank in the rearmost bay and using a macerating toilet that can
use a 1.5 inch hose to place its output into that tank. The current 35 gal black tank would become the grey tank.
It would give me about 19 toilet flushes' between dumps and allow me to just leave the grey tank valves open when in a campground with full hookups.
