ac leak

drip tray is clear and discharges out both sides (not through little pin holes) though the trailer was level, bolts are snug. it was humid as can be. did a quick clean, will get a more in depth cleaning and a filter change at the end of the season. Thanks all.

When was the last time you snugged up the four mounting bolts?

How level was the RV ? If it was leaning to the side opposite of the "Chute" it may have simply overloaded the drip pan because it was working so hard.

You need to verify that the drip tray tube is clear.

When was the last time you cleaned the filters on the inside?

What happens
The fliters clog the blower creates a vacuum in front (And behind) the Condenser that is strong enough to Suck the water out of the drip tray.

Then it drips

If you use it where you have high humidity run the fan on high to avoid freezing it up (the coils). If you drop the inside panel you should see 4 bolts 1 in each corner. these need to be snug Don't over tighten. The A/C sits on a foam gasket that you don't want to crush this is what keeps the water out from the roof. You should be able to see it when you drop the inside panel. These 4 bolts need to be snugged or checked every once in a while.
