Water leaking into rig from A/C unit can only be two things.....
The roof gasket is not sealing...either because the 4 hold down bolts are loose, gasket has been over compressed...water from rain or washing rig is pooling around A/C unit and leaking in thru gasket.
The 4 hold down bolts can be accessed by removing the whole ceiling grill and then tightening the bolts.......just snug not wrenched tight.
If gasket has been over compressed then you will need to replace gasket. Disconnecting power to A/C unit, removing hold down bolts and lifting A/C unit up out of roof opening.
The other source of water is from evap drip pan drain holes being plugged and not allowing condensation from evap cooler to drain out onto roof and run down and away.
You have to remove A/C shroud then remove metal cover over evap cooler and clean drip pan drain holes.
The fiberglass material sounds like the return air filter....should be cleaned and/or changed frequently. Dirty air filters cause restricted air flow and can cause excessive condensation
