Celestep, thank you, and everyone else for the responses thus far. Fortunately, our beds are holding up very well and I've never seen any leaks or unexpected condensation/moisture.
It was raining quite hard when we put up the beds, so I'm sure it was just leakage through the zippers. The recommendation to pull the mattresses before lifting the beds in the rain is probably a good one.
After setting the camper up and letting it air/dry out, everything looks good.
