We live in S Louisiana and it is nothing here if not humid.
Sometimes if the unit is not perfectly level water will pool where there is no drain.
If it is such a drainage problem, take the cover off, let it run an, see where the water pools.
Drill a hold there to let out the water before it overflows into your camper. (Put a block of wood under the pan so you don't accidentally slip and make a hole in your roof)
Put the cover back on and never look back.

Thanks for the info. I had the same issue on a hot weekend with my Salem CruiseLite. I thought my dealer said to use the high fan setting. Now I'll have to check to be sure I didn't hear it wrong.

1) remove the shroud on your air conditioner (both halves) and clean out the drain holes in the floor pan. If there is standing water in an area, you can carefully drill a large(er) (1/4 to 3/8 inch)diameter hole to aid in drainage. USE A STOP ON YOUR DRILL BIT to prevent drilling into your roof!

2) Remove the interior air handler cover CAREFULLY. You will need to use a razor knife or blade to cut the caulking that binds the plastic to the ceiling. DO NOT SKIP THIS STEP or you will ruin your ceiling's paper covering.

3) Examine the "torque tabs" on the air conditioner. They are the yellow tabs in the photo. Over-torqueing or uneven torqueing is usually the culprit if it only leaks during rain storms as the over compressed gasket will eventually fail on the rough EDPM roof material. Removal and gasket replacement will solve this problem.

If you don’t have a first class drill stop like the one on Herk's photo, you can cut a piece of tubing to slip over the drill bit with the right length of bit exposed. Just don't press on the drill too hard and compress the tubing as it drills through. As a backup, maybe you can slip a piece of sheet metal behind where you are drilling.
