I agree with the weight issue. The most rear tank is the fuel tank, clear at the rear of the chasse. It drives much better full then half or empty. The water tank is the most forward and I've never traveled with it full, just empty. Black & gray are left of fuel, but are usually empty. When cornering it seems that the toad is pushing the mh around and outward. You really haft to hang onto it in cornering.
