Gray tank capacity only 50 gal

[Waynehartmann]

We have a 2021 395 MS and found out our gray tank capacity is only 50 gallons. We do not have a rear bathroom so we have a 50 gallon tank in the rear not hooked to anything. Is there a way to connect our 2 gray tanks together?

I can't think of an easy way to do this. If at a permanent or semi-permanent site it might be feasible, but if you're regularly mobile it would be a nuisance to setup an exterior system to the dumps to utilize both tanks (by equalizing them). You'd also need a third "dump" in the middle to drain the water from the hose used to connect the trailer's dumps.

Maybe someone else will have an ingenious idea?

It does have a separate rear tank dump location for the rear tank but I have no way to put in any water in the tank to dump.

I wonder if the rear tank is plumbed to the WD prep and rear bathroom sink?

It is possible to pump grey water from where it drains to a remote tank location. This is a common solution for the shower drain in a boat, but is also used in RVs where a sink is in a slide. This could be set up as an overflow from the primary grey tank or set up to drain just a galley sink or perhaps the shower and automatically pump this grey water to the unused tank.
