Weird water issue and it's driving me crazy

Yes, I have....I had small windows beside each of the nightstands and when the wind blowed hard along with rain I would end up with a quater-sized drop of water on the nightstand- right about where you describe. I finally figured out it was coming from inside the window frame. No amount of temporarily taping up the weep holes on the outside made any difference. This only happened twice in the four years we owned it ('04 Jamboree 31-M). I just quit trying to fix it since it hardly ever happened but it only leaked when there was very strong wind driven rain against that side of the rig. I'll still bet it's something within the window frame that's not tight. In order to actually trace where the water came in- I had to take a flashlight and point it right at the bottom of the frame and then I could see a very small water trace coming from the bottom and traveling onto the nightstand. I never did this but you could try to caulk all the way around the outside of the window frame and then see what happens.
