Now I know why the side and back mattresses wick water when it rains.

I have a 2009 Roo 233 and for as long as we have owned it, the sheets on the side and back bunk ends (when expanded while camping) would get wet when it rains. I always thought the canvas was weeping or it was the stitching... but I think I may have discovered the real reason. Attached are two pictures with crude arrows of the direction of flow of the water.

When it rains, water flows down the outside channel of the bunk frames (on the outside of the black rubber seals (the inside of the black rubber seals is right against the canvas). On the front bunk of the camper, since the frame is angled back for aerodynamic properties, the water flows into the hinge area and pools. When it rains, I can see the pool of water in there. I will eventually pool enough where it will flow out at the corners. I made another post recently with a picture of the pooled water in there. The side and back bunks are better since the frames are vertical. The water flows out of the frame and runs into the channel formed by the bunk end frame and the folded cap at the perimeter of the bunk end. Water will continue to follow this channel to the end of the bunk end and turn the corner to part of the bunk end that is the top edge when folded up. The sides of the bunk end (where your head/feet go) have a flap that gets velcro'd down to keep your sheets away... but the end has nothing and your sheets/sleeping back can come in contact with the wet channel.... and it gets wicked up.

How much this happens and on what bunk it happens worst is dependent on how level the camper is. I watched this in action last weekend while cleaning the camper.

I'd like to come up with a way to stop this from happening. I can't add a bead of caulk because that would interfere with the bunk from closing and sealing properly. You obviously don't want to drill a hole. I was thinking that maybe I could clip on something to the bunk end perimeter near the hinge part that will block the water from flowing down to the other end.... then unclip it when it was time to fold up.

Anyone else have this problem and perhaps a cleaver fix?
