Last time I filled the fuel tank on my camper, fuel ran out from the top of the
tank somewhere.  I was at at gas station/convenience store, and went into the
store for something after filling up.  When I came out, I noticed a small puddle
under the van, and more fuel dripping down.  I investigated and found that the
fuel seemed to come from the top of the gas tank.  I left the van sitting for a
bit, and the drips decreased, stopped.  I then started it up, drove it a few
blocks, and there seemed to be no more leak.  Therefore, with rechecking
periodically, I risked driving home, some 60 miles.  Seemingly no more leaks.
Now, there it sits in the driveway, showing no evidence of leaking.  One other
point may matter.  The automatic shutoff on the nozzle failed.  The filler inlet
did not overflow, because I was attentive.  However, there was gasoline all the
way to the top of the inlet tube.

So, is the inlet tube bad?  Will I only know where the leak came from by
dropping the tank?  I think that, though I think it must be the inlet tube or
its connection to the tank.

I have never noticed a gasoline smell after filling up, and I have never had a
leak (overflow?) like this before to my knowledge.  However, this leak was
substantial.
