The side from which you fuel has can have an impact as well. Filling from the left side-more inline with the tank filler neck-I find one click gets me pretty full. Filling from the right side, I find it much more likely the pump will click off well before the tanks are full.
The angle of dangle is critical to any vehicle when filling, people blame the pumps for shutting off too soon but it is the smoothness and speed of flow through the filling tube that causes the click. Quite often just filling at a slower pace will cure the problem, never really understood the need to squeeze in that last drop it can cause problems.
