We have a 2016 Ace 29.3. There are only two of us. We NEVER come close to filling the Gray Water Tank BUT are only getting four or five days before the gauge on the Black Water Tank shows four dots. Maybe only two on the Gray. Can I only expect 4-5 days on the Black Water tank? What has your experience been with this particular model.
Please compare only this model because others have higher capacities.
Thanks!
