Yeah you have a seal problem. Or a crack. I had a serious leak in the skylight over my shower. Got up on the roof and found a crack from a hailstone. Got after it with eternabond tape and Dicor lap seal as a temporary fix until the new bubble gets here. A tiny crack lets in a lot of moisture. After you get the outer seal/crack fixed remove the inner bubble and let everything dry out real good.
Plan on dedicating all of Memorial Day weekend to fixing stuff on the camper and that's on the list.
Might as well since the parks will all be full up!
