New Motorhome water leaks

I brought our new Motorhome to the house this weekend to get it packed for an upcoming trip. We had a lot of rain here in Florida on Saturday night (3 inches at my house). When I went to take the motorhome back to our storage garage, I noticed there was water running out from under the couch and dinette. The couch and dinette are on a slide. Both of the slides were pulled in during the rainstorm.

I also notice 2 of the windows had a little water than had weeped in from the bottom of the window. The windows are double pane frameless. I am thinking I can probably fix the windows with a little clear silicon. I'm not sure what to do about the slide. I guess I will have to take it back to the dealer eventually.

The motorhome has been in the rain twice before and I didn't notice any water inside. One time we were driving in heavy down poor and the other time it rained when I had it at the house but the slides were out during that rainstorm (I have slide toppers on the motorhome). This weekends rain had some pretty heavy wind so I'm sure that made the leaking worse.

Any suggestions on how to fix the leaks myself? I have a trip planned this coming week so I am hoping it rains so I can actually see where the rain is coming in versus just seeing the water after the fact.

  • Can't fix a leak until you find it's source. Best way to locate the source is to have the rig pressure tested - cost about $100 in my area. Worth every penny.

    I guess I didn't word this properly. Water was "weeping" down the wall on the bottom of the window. It was a blowing rain and there was a puddle under the window on the kitchen counter. When I took a paper towel and pressed under the window the towel was wet.

  • the weep holes were "weeping".
    throw the tube of silicone away.

    make dealer/mfr. address the slide leaks.

  • Well, one nice thing is the motorhome is stored in a garage so the only time it would ever get rained on would be the 35-40 days a year we use the motorhome. That being said, obviously the leaks need to be fixed. I guess it's back to the dealer.

    Until you find the source of the leak, it is impossible to suggest a fix.

    Often people run a garden hose over the suspected area leaking and try to recreate the leak. That is very often unsuccessful. The best thing to do is to pressurize the RV with positive air, and then coat the RV with a soapy water. Where you see bubbles is where the leak is!
  • It's just an afternoon's job to pull the window, clean out the old bedding putty and reset with fresh putty tape. But on a new coach, the dealer should do this.
  • No clear silicone PLEASE
    You might be better off using a hose to try and recreate the leak. The leak could be dependent on the direction of the wind or rain which can be simulated by your use of the hose.

    Silicone will eventually discolor and look like cr**. New Coach I would remove the window and reseal it correctly. Why cobble a job on a brand new coach.
