Rockwood/Flagstaff - travel with full fresh water tank?

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.

It's all relative ... I've always towed with 1/2 ton vehicles properly sized for the trailers I was towing and whether the FW tank was partially or completely full has made zero difference at all in how the combination towed. I don't give it any thought at all ... because I don't have to. ;)
