If these calculations are correct, he should be able to smell that much loss by walking around his rig.
I wonder if by topping off the tank at home using his portable gas can, he may be covering the internal vent line in the tank with liquid gasoline. As the temperature changes, this raw gas escapes out the vent/charcoal canister. Unless we live next door to a gas station, most of us probably burn a gallon or two just getting back home after a fillup and therefore have a little air space in the tank.
In other words, it might not be possible to keep a gas tank completely full in an unstable environment without somehow sealing the vent lines.

That was my thought, they had a add on TV here in Vegas for a few years about not topping off your tank at the pump, when the pump clicks off that's all the fuel you need, the rest evaporates off and causes our air quality to go down during the summer, maybe his fuel lost is from filling over full with a portable gas tank every 2 weeks..
That assume that you don't burn off the excess driving home from the gas station. It could be that he burns a 1/2 gallon round trip, and the other 1/4 goes into the canister. The canister is purged when you drive it, so it does not build up stink, when working properly.
I would also suggest another possibility. He could have a stuck injector. The expansion of fuel in the tank will push through a leaky injector and drip into the intake. Since it is burnt off, it goes unnoticed. I would look down the intake. Turn the key, which will turn the fuel pump on to build pressure. It also pulses the injectors. Once the pulse is done, look and see if either injector drips afterword. If it does, the injector is sticking partially open.
