Lee, Keystone lists fresh water capacity not FW tank capacity. So 34 gal + 6 gal is 40 gal. Where is the missing 3 gal? Hard to say but if I were going to make a guess it could be that the trailer, or tank isn't perfectly level. The tanks are typically large flat and shallow ( about 4" deep) so if it isn't level it can leave a pocket of air in the tank.
