AC leaking like a sieve

The front coil is called the evaporator coil and the back coil is the condenser coil. The air in the RV is pulled through the evaporator coil and heat is pulled from the air and then cool air is returned to the RV. Are you sure you have checked the tray below the evaporator coil and know for sure that the drain holes are clear.

You should be able to pour a quart or two of water onto the top of the evaporator coil and see it run down the evaporator, then out the drain holes and then on to the roof. If the evaporator drain pan fills up with water, it then overflows and water drips out of the ceiling assembly and into the RV.

OK, this is the most help to me at this point, but I have a question: obviously, I can't access the drain-pan from inside (except to stick my fingers in to feel that it is full of water), so I am assuming I have to disassemble the shroud which covers the evaporator coil to access the drain-pan. But when I went up the first time to inspect the unit, I found that it is covered with an insulation pad (like dense styrofoam), and I don't see how to remove it. Of course, I wanted to inspect everything, but this is something I could not figure out. I will go up again and give it another go using your advice. I will check back when I finished, and let you know what I encountered.

Thanks.
