I'll agree that the small tanks aren't great. Most of the time, we look for full hookups, so it isn't an issue. When we're in state parks without sewer hook-ups and using the blue tote, it shouldn't matter that much as I only like to haul 15-20 gallons of gray water at a time. It really boils down to what compromises you want to make when you want to downsize to around 26' and 7K of weight or less. We've done a lot of looking, and at this point, figure that if a smaller unit ends up being wrong for us, we'll just have to trade it and go back to something in the 28-30 foot range.
