Bunk end water fix...cheap!

I am a machine designer living in Dover, NH. I happen to be on shutdown this week and spent some time thinking about the lousy seals that all manufacturers use for their tent ends on hybrid TTs. Actually the seals are OK its the surfaces they mate to that are far too irregular to give the seal a chance to work. Then there's the issue (with Rockwood at least) of putting poorly installed screw heads right under the sealing surface. This is a two part fix and it will stand up to a hurricane. First put caulk (white silicone) on your finger and fill every screw head where the screw driver tip goes and under every screw head to completely fill any voids then wipe them off with your finger in the direction of the seal. I have attached a link to my photo gallery that shows everything I'm describing. Now go to home depot and for $7 get two 10' lengths of 2" SCH 40 PVC pipe. I spent a fair amount if time with my CAD program optimizing the pipe size and angle of cut to get the best water shedding effect. What I have done in essence is slice a chunk out of a 90" long PVC pipe so that it hangs from the gutter over the bunk end door. The chunk I removed is 1/4 or 90 degrees of the pipe (see photos). The effect this has is that all water now either goes into the gutter or off the front of the pipe without any chance of getting to the top horizontal seal. I don't care how careful you are at closing those ends, THEY WILL LEAK! The water on the top edge just doesn't go off either end it seeps past screw heads and irregularities in the paint and welds and ends up on top of the main inner seal where it finds its way to the tent material and bunk end where it rots the wood. We had a good rain storm last week but not anything serious. The next day I stood on a ladder and dried up the exterior water from the outer seal. My wife then opened the ends very slowly and there was plenty of water sitting on the big black inner seal and water that had made it to the tent itself (only on the front angled bunk). This is a three week old 2010 19' Roo. Supposedly with the best seal system currently available. My solution is to keep the damn rain away from that top seal, problem solved. I have found that the vertical side seals actually can work only of you make sure there isn't anything causing gaps that the seal can't adjust to (like screw heads). I am currently working on a tie-down system so I can travel with these in place because the wind driven rain while traveling is also an issue but I think I have a way to do it completely safely. More to follow. I hope this helps and cuts down on the thriving bunk-end replacement business ;-)

For all photos of this project...

I like it! Simple and effective! Keep us updated on the tie down system

The 1959 Buick 2-door had a framlees window with a chrome "visor" that was Spring loaded. When you opened the door,the visor would flip up out of the way, It didn't matter if the window was closed or not. and when the door was shut the visor would flip back down into place. If you and your CAD could design something like that and get a copywright on it, you could make alittle bit of change...

The travel bracket is in the works now. Stay tuned.

I finally got around to making the water shield hold-down straps. I can't imagine a condition that these could make these come off now. I tried many methods of securing these while traveling because towing in the rain always causes a leak along the top even with the extra caulk I have added. With there installed the bunk end seals are no longer an issue in any conditions. Hope this help someone else.

SPRING NOTE:::::::
I have found it necessary to add one last line of defense after this springs flooding rains. Take white duct tape and stick it into the little (as in useless) gutter above the door then attach the vinyl so that it hangs over the gutter as a flap. This keeps any water that ends up under the tube to still fall past the top horizontal seal and down the door face. The tube with nylon straps keeps this in place while traveling. An additional benefit is with the tent end out this flap hangs down to keep rain away from the top edge of the tent material where it meets the camper body. The pictures will help explain this.

bunk end seals

I had 08 roo 21ss .I took all the round head screws out i took a driil bit and counter sunk all the holes a bit i then put flathead stainless steel screws in every hole they were all nice and flush put some clear seam sealer over all the screws sealed great with new white seals.I now have a 2011 rockwood ultra lite 2304s.

The rest of the story...

It was the day to wake up the beast and I was able to take some photos of the last and FINAL "water in the bunk ends" mod I have made. This is in addition to the PVC pipes shown earlier in the photos. With this addition a garden hose on full (from above) causes NO leaks. Although the pipes helped there is still a hard enough rain that can overwhelm the system. The photos on PhotoBucket are in reverse order so go to the last page and work backwards.

The rear (vertical) bunk end has had a flared lip added just above the hinge with some white duct tape and the vinyl bathtub edge sealing material you can get at home depot. This small lip deflects the worst rain from getting into the hinge. At the top I used white duct tape, with half of it tucked into the gutter (clean with alcohol first...you and the gutter) and the other half stuck to a 4" wide continuous strip of clear vinyl. What this does is that no mater how hard the rain, any water that gets past the PVC thing stays completely away from the top end seal and just pours down the door which is half of the battle with these things leaking.

The front bunk I did the same thing with the vinyl at the top and went one extra step at the bottom. To keep wind driven rain (while driving) out of the hinge area I used duct tape, the bath tub stuff and velcro to close off that area. This might all look like a bit much and that I need to find a hobby but at least my bunk ends aren't a spongy mess and come selling time it should pay off.

In addition anyone with an 2009 or newer Roo is probably aware of the singing propane tanks. There are two photos of the labels on the pigtails that Rockwood sent me. I can attest that with water heater, cabin heater and all stove burners running the sound is completely gone!

Note:

The positioning of the front end's velcro is important. If it is any higher the bottom bunk edge chops the vinyl up. Where I have it the vinyl just buckles when the end comes down.

Good luck all!

Although I hold little hope of ever getting my 23ss repaired, if it does happen I will use your good ideas to help prevent future water damage. If I had only known the bunk end problems when I bought the Roo in 2007, or if Forest River or my dealer had notified me of the problem in 2007, 2008, 2009, or 2010. Words fail me. Again, thanks for the good idea.

Pixleys - I would like to see the mods you have done to your bunkends, it appears all the links to photbucket are broken or have been remvoed. Is there anyway you can post them again to someplace? I think i have a good understanding from reading the thread but pictures sure would help :-)
thanks
