Fuel has weight. Depending on the location of the tanks, it can shift the balance of weight, increasing or decreasing how hard the tongue of the trailer presses on the hitch. Too far in either direction could make it unsafe to tow the boat/trailer.
The tongue of the trailer presses down on the trailer hitch, and that is tongue weight. How hard it presses down is a function of the weight in front of the trailer wheels, and how much of the weight is not offset by the weight behind the wheels. If the tongue weight is too great, the rear of the towing vehicle goes down. Too light, and the boat trailer will swing side to side.

Some people bite their tongue while they are sleeping because they are relaxed. They can also have a bigger tongue than usual.
Maintain solid contact between the tank and the spout.
It's always smart not to smoke while near fuel or gasoline.
