Leak from return air vent

We have had a lot of rain (5+ in in 24 hours). I have water coming out of one of the return air vents. Does anyone have any ideas? It is suppose to be nice tomorrow so plan on pulling cover off the AC unit and check caulking. It is a 2016 Wildcat new last May.

The AC has a foam seal around it- usually you pull the cover off on the inside of rv and there are 4 bolts that pull the AC down to the roof and sandwich it.

Rmk is correct, you'll see nothing from the outside.
There is no caulking.
There's a dense foam gasket between the a/c unit and roof.
Remove inner grill and make sure the 4 bolts are snug.
Iirc the torque on them is 45 Inch lbs .

There is no inside cover, this is a 5th Wheel with ductwork for AC. The water is coming in through a return air vent.

I'm confused?
This is not what you have?

I have ductwork just like central AC does in a house.

The vent closer to floor is return air, should only be one, everything on roof is discharge

Nope... not correct for OP's Wildcat. I also have one. No part of the AC unit is visible from the inside. His '16 vent covers are fancier than mine but there are two (2) return air openings for each unit and they are each in the ceiling (not single, not low) near the side wall as shown in his pic. I'll take a pic after the sun comes up. I'm afraid a lion will eat me if I go out now!
That said, I assume water is getting in from the outside and running down your racetrack duct to the return air vent. You may have to take off the outside cover and give a look.
