Water lek issue

My first time at this site.

Thought I would share an experience with the Cougar 331 5th wheel trailer.

I noticed that the underneath of the trailer has a kind of cardboard type enclosure that keep critters out. It was bulging downward an appeared it was full of water. I new it was not from my on board water system as everything is pink with rv antifreeze, this was clear water - rain water.

I removed the holding screws that holds the undercover at the very back of the trailer and was shocked at the amount of water that came out.

Bottom line is that the wire plug on the rear of the trailer had no sealant or clay type material, so leak number 1, number two there is a wrap type material that must be used under the floor decking, then laid onto the trailer frame it was full of water, meaning the wood floor has likely absorbed so moisture.

And Leak 3 the water dripped down to the underlayment and caused the noticeable bulging of the under carriage.

So we love the trailer and I will fix it myself, and properly correct the leaking. Check you rigs under carriage if you have one, standing water is no good anywhere on an R.V.

Thanks for the time.
  • blofgren - Yes the outlet box to plug the trailer into power is on the outside wall by the bumper, no sealant, and the metal strip that secures the bottom of the back outside wall( it has screws all along the bottom and then the screws are covered with a plastic strip). has several spots with no caulking, so I'm guessing that's what allowed the rain water to enter the inside of the coach.
  • +1 on what Jim said. I had a water leak on my Minnie Winnie and I finally tracked it down. Could have been the reason why my entire unit "fried" since the leak was near the converter box. I'll never truly know, because we traded up to and Arctic Fox and then onto a super great Lance. Good luck finding that leak and repairing it!

    Oh, on second thought, I think your Cougar has OSB flooring, and once that stuff gets wet, it tends to rot like hell. So good luck!
  • Hi, that really sucks. Water leaks can cause a lot of damage that you didn't expect.

    I am not understanding where the leak started; was it at an electrical or cable outlet on the wall of the trailer?
  • A water leak must be one of the toughest things to find and often the easiest to correct. You only see where the water appears - not where it started. But once you find the starting point they're often (but not always) an easy fix - if you have the proper part.
