Since my fuel economy is very high (63mpg in interstate cruizing) the net range per tank is still over 200 miles.
I would guess the F800GS can deliver similar results.
I agree on the placement being handy for not unpacking to refuel, although the low side high side issue is at odds. Like I said on the center stand is the way I always fuel up, and based on that I'd prefer the dismount side be the the pump side.
