3/4 gallon per week would be a small leak, you know. I make that out to be about 8.4 drops per minute. (assuming a drop size of 30 per ml, common for water, not so sure about gasoline)
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.
