A/C Cover

took the shroud off today... other than finding two stripped out bolt, yay, spring project, didn't find anything obvious.

Ran out of time, as I needed to get it winterized before temps dropped and take it back to storage facility. This really was a driving rain.

I'll get out there this winter and look for the big bolts to tighten down.

Thanks Itsy that is what I thought.

To the O/P they will not fix your problem for that's not where the leak is. If it's leaking it's under the A/C the gasket between A/C and roof. and as others have said. remove the LOWER cover (inside the RV) and check the gasket and the 4 big bolts. Odds are a turn or two all the way around will fix you up. IF NOT then you may be in for some serious work on the roof. This requires REMOVING those same four bolts. then removing the A/C and replacing part or all of the roof.

1. The OP is talking about aftermarket vinyl AC covers
2. Others are talking about the AC SHROUD
3. The Aftermarket is designed for storage and to keep critters/insects out of the AC system. It is not designed to be ON when traveling. There is no reason to have it on when traveling.
4. The AC Shroud MUST be installed to keep the system water tight. There are small gaps thruout the AC that if unrestricted, water is allowed to get to those areas you could have a rain leak. On some AC units the shroud MUST be installed to route the air thru the Condensor. If not installed the Compressor will overheat. Doug

Have you retorqued the A/C hold bolts recently? They can work loose a bit over time, letting condensate or rain leak in past the seal.

Odds are that this is your problem.

The top (above the roof) part of the A/C is water tight even with the shroud removed it should not leak inside. There are both the outer Shroud and the inner covers (2 of those) one over the condenser fan area and one over the evaporator and blower area.. IF you take the outer shroud off and run through a car wash with water cascading down on top of it you should NOT get any water inside for that part is "Sealed" between the inside and outside except on some very old units with "Air intake" controls and even then if the intake door is closed.

There is a gasket UNDER the A/C. the mounting bolts need occasional re-torquing (3 long bolts inside the RV.. Usually...) and there are a few ways it can APPEAR to leak even though it's not leaking.

OK but mine had a small rain leak w/o the cover from the blower and not the roof gasket. Somewhere between ideal and practical there are areas that may leak so it's likely best to have the plastic cover instaled.

They are similar to the flexible wheel covers but fit over the ac shroud. Some have elastic bands, others string pulls. They are not designed to be used while traveling.

here's an example
AC Cover

Had an A/C cover once for use when unit was in storage. After one of our frequent wind storms it was gone, never to be seen again! That was the first and last cover.

Before you go on the roof, the bolts to tighten the A/C unit are inside the coach and these should be checked first.

I agree with the bolts bring loose. We had a new AC put on the front of our 5er and only leaked for me and not dealer. Finally, realized it was loose and shifted slightly in travel which allowed it to leak only sometimes.
