Just wondering what the thoughts are on towing with full or empty water tanks when going to a destination with water supplied? Our 20.64-1 has 3 x 85 litre tanks, so that's about 255kg. The limited tows I've done with this van have been with all empty, all full and last time front two tanks full, back empty. Didn't notice enough difference to comment on, but my BIL reckons they tow better with tanks full. What's the general consensus? I'm thinking if you don't need the water why lug the weight. Or maybe just fill the front 85 litres for some more ball weight?
