Magic water leak

[haiduan]

I have a 2021 Alpine 3700FL. Have had 4 occurrences of water showing up at the base of the bed after a rain - typically over night. Two spots on the left base of bed, two on the right. No indication of where its coming from. Can't figure out where it's coming from - AC vents? Not coming from under bed or next to walls. Any advice would be appreciated.
