Does anyone here know the capacity of the black waste and the 2 grey waste tanks on a 2005 Keystone Outback 30FRKS? I've looked everywhere and keystone support could only give me the fresh water.

Looking at the size that came in your year it looks like they are 35 gallon tanks.

According to the specification information on the Keystone website: https://www.keystonerv.com/travel-trailers/outback/specs/ According to the specs, there is only one gray water tank in the 30FRKS. Tank sizes per the specs:

Fresh water 50 gal
Black tank 30 gal
Gray tank 30 gal.

Definitely 2 gray tanks kitchen and bath. Probably refers to each tank. I looked hard for those specs. I really appreciate your help. Just what I needed
