Anyone know the size of the 2 grey water tanks?

Welcome to the forum!!

Specs call for one 40 gallon gray water holding tank https://www.rvusa.com/rv-guide/2023-...an-29s-tr56167. To confirm, take a look at the number of dump valves..........should have one for black and a nother for gray. If in doubt, obtain build sheet from Entegra customer service based on the VIN.

Yes, I know the specs say one, but the control panel shows two gray tanks active. Outside the coach the normal gray/black valves & then back behind the wheels is another valve for the second gray tank.

Install a turbine totalizing meter on a hose and run it in the sink that the second gray tank services and fill up the tank to confirm tank capacity. That is I do.

On my 2022 29S, the second grey tank is only for the outside kitchen sink and is pretty small...I saw the tank heater sticker on it but no capacity plate.

My guess is pretty small maybe 8-15 gallons or so. It has it's own dump valve and outlet too behind the back wheels.

Hopefully it's pertinent info though a different model year. The brochure for the 2022 model year doesn't mention the second tank either.

The second gray tank is spec'd at 9 gallons and is (as others mentioned) only for the outdoor kitchen sink.
