Leaks, and more leaks

Is it just my bad luck or a nature of the beast? Seems anymore all I do is chase leaks in my trailer. So much that I even built my own seal-tech machine to pressurize the cabin and and spray the outside with soap.

First was the front gutter extension leaking behind the drip edge into the front closet, next was a leaky window frame, then the caulking (which looks very much like factory applied silicone) leaking along the top of the slide out bulb seal, and just recently the rear gutter extension leaking in the exact same place the front did. I'm almost wondering if covering the trailer in the winter pulled down on the gutter extensions enough to break the old caulking seal?

Is it brand related? I know the Zinger brand ain't no Newmar! Miles of driving on poor roads? My friend has a 10 year old KZ that has never leaked. It doesn't move much however as it's at a permanent site. Or am I just over cautious checking?

I guess the good thing is I've become proficient with a caulk gun! Also I've been a ProFlex user for a long time until recently when my local shop didn't have any. The tech recommended OSI Quad from Lowe's. Much easier to work with and half the cost.

Just had to vent!
  • I would recommend anyone that has gutter extensions to carefully inspect the seals around them. After pulling mine off I could not believe there was nothing behind them. You could see right down the backside of the drip edge with the rubber roof folded over the side, and the screw hole where water was seeping in.

    Was contemplating not using the cover this winter because I am sure it was the cause of pulling the extensions away from the oem sealant. Then my wife said I'll get icicles pulling on them then. Guess it's just another item to add to the check list!

    Pressure testing is the only sure way of finding these sneaky leaks.

    Even a pinhole leak can be a lot of accumulated trouble. You found the best way to find the leaks with the pressure test. It may be effective for you to pull trim pieces and seal them again, it depends on the quality of the original sealing.


    Huh-huh. You said "quality of the original". Lack of quality is more like it. TT's aren't "better" or "worse", they're "worse" and "even worse than that".

    Well, it's all bad if you plan to sail it across water but what I was getting at was that some trailers seem to have a better sealing schedule regarding the butyl sealer in windows, the types of sealers between trim pieces and walls/roofs, etc. If I knew then what I know about Eternabond tapes, now, when I pulled the trim pieces on mine, there would have been a piece of the Eternabond underneath, on every joint.

  • Luckily the roof is great and has not been a problem. Not too many places for it to leak and Dicor/Eternabond works wonders!
