Found pretty much the same thing on our Classic...when FW tank is full, constant drip until level falls below lower vent hose connection....hose leaking around the clamp.
I can see it but can't get to it without major interior tear down.
If the clamp had been a worm style instead of crimp I think I would be able to "git-r-done".....oh well SIL.
Now listen real hard and shut off when it starts to gargle, or wait till it spits and drain some out.
