All of your tanks are small.........that is typically due to lack of larger spaces to install tanks

Install an addition 3" dump valve on common drain header.
Close it...open black/grey and combine them for 56 gal waste tank capacity
Grey is just as nasty if not worst then black....body oils/sloughed skin cells, grease/oils, food debris, urine etc
RVs use to just come with ONE waste tank.
I have 3 waste tanks on my 5vr...added the extra common valve when first bought it back in 2006 (128 gal waste capacity)
Previous 5vr added the extra dump valve
Simple easy means of increasing waste capacity
Or buy the twist on version that goes on end of drain pipe.
x2 the nice thing about this is now you know you can fill the water tank and know you will not overfill the grey or black tank.
