I am camping in the Louisiana heat and humidithy - LOTS of humidity - and condensation from the air conditioning unit is dripping into the trailer. Air is not ducted, so it is dripping from the unit itself and then being blown by the fan. Needless to say, I am not a happy camper right now. There is still some condensation dripping off outside where I would expect it. I recently had the top of the trailer inspected and resealed, but I suppose they could have missed something. I'm wondering what other possibilities you might suggest. Thanks so much.

If you search this Forum you will find a suggestion to tighten the four bolts that hold down the A/C. We did and did and the dripping stopped.

I am in a high humidity area as well. Condensation, and sometimes ice, does build up on the cooling coil (inside air flowing across it) of an air conditioner and there are channels that direct it outside, and then runs off the roof. This is especially prevalent in high humidity. My solution is to run a dehumidifier while the air conditioner is on. I have no ice buildup and there is less water dripping outside. I can even run the air conditioner on low fan, making less noise. A side benefit is that the air conditioner runs a little less often. I believe that dry air is easier to cool than wet air.
You might also take the cover off the top and look to see if the run off channels have any debris in them, causing them to overflow and then leak inside.

Dripping inside can be from 2 sources. first the roof gasket may be leaking, and you see this if it rains. Tightening the 4 hold down bolts is the first thing to try, second is a new gasket. The second source of water dripping is from the evaparotion coils just above your filter. If your coils is dirty, the air flow is restriced and will ice up, causing water to drip inside. Pull the filter and make sure it is clean. Look up inside and you will see the coils. If they are full of dust, hair etc. they need cleaned. once they are clean, the next step is to get on the roof and remove the AC cover. There is a drain hole on the bottom off door side of the AC unit, if that hole is plugged, water will flow back inside. Muddabber/wasps love to crawl in and make nest on the coil. If all this doesn't fix it, you may have to remove the sheet metal cover that covers the evaporation coil, about 6-8 screws to remove and then carefully work the cover off. There is a foam tape that they use to seal the cover, so you want to try to save that seal of find another way to reseal it. Once the metal cover is off, clean the inside of the coil, and make sure the drain hole is still clean. reinstall the metal cover. While you have the main cover off check the rear coils and make sure they are clean, and if any of the coils are laid over, straighten them out. Put all back together, and start it up.
Also to remember that in high humidity, the more you go in and out the door the harder the AC has to work to keep the humidity down.
Hope this help.

I had this with a leaky roof gasket. For some reason it did not leak in the rain but would drip with the AC on.

If you adjust the four bolts others posted about, note that you are not supposed to tighten them too much - just enough to compress the gasket.

Just having a DIRTY FOAM FILTER will cause this as well... if you pull down the overhead filter cover and look around in there you might see what is happening. You definately can see the four LONg SCREWS mentioned and they do work free. They should compress the large 14x14-inch gasket that sandwiches the top and bottom halves together. Bumpy roads vibrations on I59 in north ALA worked mine loose...
I sometimes have condensation on just about anything metal inside the pOPUP when it is real humid outside. I always run a couple of fans inside to prevent that...
I have also had my unit freeze up especially when I ran it all night long... Not much you can do there except turn it off for a hour so and let the ice melt away...
Another thing I always do also is when I setup I am level front to back but I usually do the side to side so that it will allow water to flow off the back of the roof to allow more drain from A/C. Not much mind you maybe one-inch or so......

If it is not raining, it is unlikely that you have a gasket that is leaking. If you do fool with those bolts to tighten it, be aware that over tightening will destroy the gasket and make leaks where there were none before.
Since you state that it is condensate, I tend to believe that you know what you are getting. There are drain holes from a condensate catch tray on all RV air conditioners and they do become plugged or partially plugged. Very likely that is the problem with yours and it needs to be cleaned. Just how to address that problem will depend upon what make/model of air conditioner you happen to have.

I have also heard to crack a vent. Yet have also heard only to crack a vent in the winter. Any thoughts there?

Pan below evaporator coil should have some drain holes --- when they get plugged the water will fill up the pan and the overflow will cascade inside the rig. Unplug the drain holes. If you don't have water issues when it's raining then I would leave the gasket alone.
