When the light comes on - how much gas is left MAY depend upon much you put into the tank the last time you filled it.
Our Ford E450 55 gallon tank will take about 5 gallons more after most station pumps stop. I can slowly trickle-fill after pump shut-off and get at least another 5 gallons into the tank whenever I fill up. I always try to do this so as to get more travel miles between refills and to ensure we have plenty of fuel supply margin for running the Onan generator should we decide to dry camp.
I have gotten 7 gallons in my tank using that method. It sure makes a difference.
My mechanic just loves people that do this,that means that eventually they will have to have their evaporation/charcoal canister replaced.
They are designed to capture vapor but when overfilling they get full of gas and fail,This will lead to a poorly running vehicle, higher emissions and eventually a costly repair bill.
The vent tube does not fill with gasoline, the tank does. The vent tube is higher than the tank. Charcoal canisters are old school, the new style components are located in the frame rail and it will not have an effect, the vent is still venting.
The other issue with filling a large motorhome tank is that you are blasting a lot of fuel into what is essentially a coffin sized box. I can let the pump click off, wait a bit, then pump several gallons in, without slowly trickling anything. Just my guess, but between the action of evacuating the vapor to make space for fuel, and the fuel splashing and sloshing into the large box shaped tank, it takes a while after the first click off, before everything settles down to the point that it's ready to accept a few more gallons.
