I drive a 2000 Chevy S-10, & I personally think this is another "my girlfriend keeps telling me" piece of mis-thunk wisdom...(but I dare not reveal my thinking to her...)

On this particular model, G.M. is indeed having some sender/float issues.
But the real issue is that "topping off" causes much more damage to the EVAP system of your little trucklett, and can be very expensive to repair.
Over-filling of the fuel tank causes fuel to back up into the charcoal canister, "flooding" it.
This usually causes the charcoal to deteriorate and fragment, causing some of it to migrate through the control system and valves.
When this occurs, valves are damaged, and the system will no longer function properly, causing the "Check Engine" light to illuminate.
Until the repairs are complete, and the system works properly again, and the light is turned off, the vehicle won't pass its emissions test.
It is best to just stop the fill-up when the hose clicks off the first time.

There is a float in the tank that is part of the fuel gauge sending unit! It is not going to be damaged by filling the tank to the top. It goes to the highest point that it can, and "floats there without a problem.
If you can not tell your girlfriend that she is incorrect about something as trivial as this, you you may want to look for a new girlfriend!

Forget the float - most of the new vehicles (and yours qualifies) have emissions systems that basically require you to stop filling when the pump shuts off. Overfilling doesn't help it - in fact it hurts it - and the pressure between the gas and the cap is important too - that's why a loose or faulty gas cap can trigger your check engine light.
Just fill up until where it shuts off normally.

yes they still use a float assembly in them,and it wont damage it keeping it full ,i have seen a few cases where they would get stuck around the full mark,but all you have to do if this happens is tap on the side of the gas tank it usually frees them up,good luck hope this helps.

No, but you really don't need to top off the tank once it shuts off. The space left over from when it shuts off allows room in the neck for expansion due to heat.

yes there is still a float in the tank and no it won't hurt anything.

If the float could be damaged, how could the vehicle go over bumps or up hills?

Thats a pretty good question.
I know me personally I fill my tank until it almost spills out.
