I'd make the argument that 2/3 full is worse than full. If the tank is full, it doesn't slosh so it's dead weight. A sloshing tank will act like a slide hammer on the tank hangers.
I found this out the hard way when I was a kid driving a farm truck with a water tank on the bed. It was half full I stopped at a stop sign, and the sloshing water bounced me out into traffic.
I'd make the argument that since I replaced the Lippert garbage with supports made from rolled angles that are not much heavier, I have not had a problem in going on 3 full seasons no matter how much water was in the tanks.
I have towed with varying amounts of water in tanks with no issues when it comes to stability, sway, feel, or anything else in this and 3 prior trailers. I suppose if you have a setup that the tail is wagging the dog or borderline to it, you might feel something. A prior Keystone trailer had a 30 gallon tank in a dinette bench sitting on the floor, higher location, between running gear and hitch, and on one side, and no issues with tank half or 2/3 full either.
