I don't think I have autofill.  What i do is when I get to a park that I will be staying at for several days I fill the tank using the top hose input.  Then I put the hose up.  I can go for a week with a full tank. When the tank gets low I will fill it up again.  I don't know what autofill looks like.  I do have a hose input on both sides at the top and a hose connection at the lower down if I ever need to just leave the hose connected.  I'v never used the lower connection.
