We went on a 4 day trip and discovered the black water tank on this model only holds 26 gallons. Also, the bathroom sink drains into this tank so it fills quickly. I am surprised that Thor down sized this tank as most other ACE models have a 40 gallon black water tank. The question to other 29.3 owners, 30.1 and 30.2 owners is how are these small tanks working for you? No other problems ... it was interesting that the gray water tank was only about 1/4 full when the black water tank indicated full. Also, I wonder if anyone knows for sure if the shower is going into the black water tank.
