As I see it, you could be building up a potential problem without realising it. If there is any water, it will sit in the bottom of the tank and only present itself when you are draining the dregs of the tank.
I really don't understand this argument.
Water will sit at the bottom of the tank.
The fuel pickup pipe will be at or very near the bottom of the tank.
I can't see "how much fuel is in the tank" will affect water being picked up. The fuel pickup height does not change with the level of fuel in the tank.
I totally agree with having a water trap and I can see that keeping the tank full will reduce condensation. But even if you do not keep your tank full and you get condensation, the water trap should take care of it. Assuming you check regurlarly and drain if necessary.
Just to reiterate, I did not bother keeping my tank brimmed, although generally more than half full and I never had a water or bug problem.
