Major water intrusion in the front floor board of the cab

What is your question?

I have started noticing my floor being wet several days after no rain so I began watching closely. We just had major rain storm and my floor board is standing water after driving 140 miles. Truck is a 2017 F-250 super cab What seems to make the problem better or worse? Rain How long have you had this problem? Last couple of months have noticed it
