Good guess Chuckster!
Okie - we previously had a Challenger (different model), and the "total" Grey Water was 77 gal... same as shown for your 34saq. Our galley was approx 38 gal, so I assume yours is most likely similar. Unfortunately Keystone no longer has the Challenger info in their archives, but here's some links which may be helpful.

Happy trails & hope this helps,
