Rainy season leaking

[paulitzlee2]

I have a 14-foot Fun Finder 2006 X139 travel trailer.

This last rainstorm in Sacramento, I realized it was leaking.

1) It was wet by the windows. The windows were closed. It’s wasn’t too bad, but it was wet. The bed was wet by the windows, but not soaked.

2) I also noticed some brown streaks on the inside walls of the trailer. I’m not sure if that is from a leak. There used to be brown streaks on the OUTSIDE of the trailer, before I washed it.

3) Brown, rusty water was dripping from the A/C.

The trailer wasn’t too bad. It wasn’t flooded or anything. We had to mop up water from the floor and remove the mattresses for them to dry. A few rags were all it took to soak up the water.

Is it possible the windows just need re-sealing? This never happened before.

Is it typical to leak water through the A/C? Could there be major A/C damage, like rust? The water leaking was a rusty brown color.

It could be the caulking around the edge of the roof and the seal under the air conditioner.

Sounds like you have more than one area leaking, the air conditioner has a rubber seal. our old unit leaked around it, but it was an easy fix. Remove the inter cover of the A/C unit should be held by a few screws. ours had four bolt heads and tighten them, I also used a silicon sealant on the outside, remove the outer cover to see the flange area seal all around it. The running down the walls from the window, I would use a hose and spray each window, if leaking use a good silicon sealant around each window check for cracked damaged caulk, also check the roof attaching to the side walls.
You didn't mention if it had a rubber roof, if so be sure to use a sealant specific for rubber roofs. Just my 2 cents worth. Keep us informed of your repairs.

IMO the best way to seal your windows is to remove them, remove all caulking, use butyl caulk tape to make new seal-leave no gaps, then replace the window. 2) I also noticed some brown streaks on the inside walls of the trailer. I’m not sure if that is from a leak. There used to be brown streaks on the OUTSIDE of the trailer, before I washed it. 3) Brown, rusty water was dripping from the A/C. If the water is coming from directly under the A/C unit there are two things to check. First is the drain holes in the drip pan under the coils, they must be open or water will build-up and overflow into the trailer. Second is the sponge seal between the A/C unit (under drip pan)and roof. Over-tightening the bolts will often cause the seal to leak, as will age. The 4 "bolts" should be finger-tight. This allows the seal to have room to flex with normal movement while driving. The trailer wasn’t too bad. It wasn’t flooded or anything. We had to mop up water from the floor and remove the mattresses for them to dry. A few rags were all it took to soak up the water. Water damage is the most common cause of RV damage. It will rot wood behind walls, cause mold and mildew to grow inside walls because it cannot evaporate easily, and cause bonded walls to de-laminate. Is it possible the windows just need re-sealing? This never happened before. Is it typical to leak water through the A/C? Could there be major A/C damage, like rust? The water leaking was a rusty brown color. The discolored water may be due to rust in the drip pan, caused by plugged drain holes.

IMO using anything containing silicone is a waste of time. Butyl tape for seals between surfaces, and Dicor sealant on everything else.
