My husband and I just repared two awful leaks from our TT (both rear corners). When we saw the damage, we realized that this was a leak that had been going on for a while (lot's of moisture, rotten wood and even ants). We pealed-off part of the rubber roof, replaced all the wood (and added even more for proper support), insulated material and re-applied the roof with Dicor rubber roof glue. To make sure that our TT didn't leak anymore, we used Eternabond tape and lot's of Lap sealant to cover all seems and other possible areas where water could leak through. We didn't cloe off the interior of our paneling inside in order to make sure that our repairs were done right and no water was coming in.

This past weekend, I went to our campsite for one night and noticed that there was a small water stain and a bit of moisture on a brand new 2X4 that we had installed in one of the corners that had been leaking?!? We have no ides ho this water/moisture came in.

Is it possible that we missed something? Is it possible that the condensation in the TT (since we had to heat the TT cause it was cold outside) caused this water leak? What else can we do in order to stop water from coming in or preventing moisture from gathering in that area? My husband is about to blow-up the TT with dynamite if these types of issues pop-up!!!

Please help!

Take a garden hose and get someone inside to watch as that area gets hosed down. Thats my only suggestion. If it leaks obviously you missed something. Pretty hard to diagnose without actually being there.

Not sure what kind of TT you have, but I took every screw out of mine and dipped them into 5200 calk and put them all in by hand. i was amazed how many screws were rusted due to water weeping thru. It was really bad along the roof trim.


Full timing it since July 2012

I have a Salem 30ft TT. After reading many posts on condensation, I'm thinking that this might be my current problem and may have been my problem all along. Since we camp in Québec, Canada, the tempertaures at night fall to 41-50 F and we heat-up the place to the point that all windows are full of condensation the next morning. We wipe of the condensation from the windows but nothing is being done about condensation that might of occured elsewhere (in walls and ceilings)?

I rebuilt my TT and used more than a dozen tubes of sealant and two rolls of Eternabond tape. When I was done, I performed a pressurized leak test and found about 20 pinhole leaks. None of the leaks were under the Eternabond tape.

I would suggest you do this type of leak test. You would then know if it's from the outside or from condensation.
