Probably water getting in at cracks where coroplast is not screwed down tight or lousy fit. But to be sure...
1 Pressure test plumbing to psi to what year model your RV is supposed to tested to. If any leaks found, fix. I have one RV that supposed to hold 85 and one that standards are 55 I believe.
2. If no leaks...think like a rain drop and see where you could get in at. Don't forget wheel wells and drain side of plumbing.
2. Then Remove that insulation. Replace with foam insulation. Type you have once wet mats up and lays down, never to come back up or insulate right again and will soak up water, little alone ever dry out. (Well maybe 3 months in AZ with fans 24/7) Replace screws with something bigger head to get better grip on coroplast when putting back in, if your screw heads are smaller. Local sign makers sell that stuff cheaper than RV places, if you need any. Foam board not as good as insulator IMO but doesn't care if it gets wet.
Then seal every crack to seal out water with whatever method you choose. From strong duct tape (gorilla) or (what ever works for you).
Don't rip out insulation in a mad fit. When pulling it out pay attention to where it is the wettest at, might give you clues to where water is getting in at. Might be nothing more than water getting in where is screwed at sides, but you won't know till you dig in.
You'll also get to see just what a "polar" package is.
Just my 2 cents.
