07 Dakota Wet Passenger Floor

Just recently bought an 07 Dodge Dakota and noticed last week my passenger side floor was wet. At the time of this, I had the windows cracked during a storm so thought that was it and cleaned it up. I should also mention I did not pull the carpet up completely this time because I thought it was minor. However, I drove the truck on a 4 hour round trip drive over the weekend and noticed again the floor to be completely saturated, this time with no rain. I have read there is issues with the ac drainage line in the dakotas but the threads I see that on are on the older generations, is this still common in gen 3? Or should I start troubleshooting else where? Thank you in advance.
