We are in the florida keys and it is extremely humid here...surrounded by water. We leave in less than a week but for now the AC must be running constantly. It is 89 degrees mostly. The AC is new installed last june and used first time in february of this year in florida but not the keys.
He is also going to call DOMETIC today.

Two ideas. the FIRST is CLEAN the intake filters I have had that issue several times when I'm lazy about cleaning the intake filters and ONE time it was not so my first suggestion is CLEAN THE INTAKE filters. and I can tell you when the blower shuts off it is kind of "Niagra Falls" under the A/C. if that's the problem.. If you need to know why. ask.
WHY...it is niagara falls when we shut it off. Running without the filter is only a temporary fix until we figure out what is wrong? NO DRIPS this morning without the filter but yes, I know we need it there and why.WHY...it is niagara falls when we shut it off.

Now the other problem.. For this you need to go up on the roof. Pull the shroud and do two things.> Clean everything (might as well since you are up there anyway This includes the condenser coils (On a Dometic I suspect the side that gets dirty is the fan side.. not easy to clean) inspect to see where the "Drip Lip" is (may be on one side or the other or the "Rear" (condenser) side of the A/C.
The one time it was not Dirty Filters the RV was not quite level. the drip lip on that unit was on the rear and I was nose down a couple inches. Lifting front fixed. but .. like that was one of several so I do not think that's it.
Icing of the fins can cause a slow drip drip that will go on for some time after you shut it off.. But not as likely to "Niagra Falls" type downpour.

Could be Evap Drip Pan drain holes are just too small to handle the High Humidity --- condensation is accumulating faster then drain holes can remove THIS SOUNDS POSSIBLE.
While A/C is running the excess condensation is being sucked up by fan and blown into ducts --- then when fan stops a wave of condensation drips out

We took the filter completely off and left it open. It is much better now without it on. He still needs to go up and find the drain holes to see what is up with that. Still a little water seeping out under the on dial over time but not the cascading water when we turned it off.
Thanks, old biscuit.
