Prime Time Avenger front leak warning

This is an informative warning to anyone who has this specific brand and line TT. We purchased ours new 6 months ago and during our first trip driving in the rain I noticed water in the front storage and the master bed / mattress was soaked. As I knew this would be a big issue and did not trust any dealer to try and fix under warranty, I decided to remove the entire front wall interior of the master bedroom myself. I don't have time or patience to complain to the manufacturer, going back and forth in emails, calls, etc. I am just not that type of guy. Maybe 20 years from now I might, but as I have the know how to fix myself, I wanted to know what the problem is.

Everything was soaked. Insulation, framing, etc. So, after having a friend spray down the front with a hose ( using the fan pattern to mimic the spray you would get from driving) all 3 seams from the corrugated sided instantly leaked, and leaked bad.

From the outside I installed a foam backer rod through the seem and stuffed it in with a plastic scraper. I then installed a second backer rod just because. Finally, I chose to seal with a high quality 100% silicon caulking. Then I proceeded in sealing the entire end channel from top to bottom.

Once the caulking set, I tested again for a long time and even used the stream function on my hose spayed, nothing leaked.

So, if you have this specific TT, I would ensure yours is water tight, or at least pay attention when you drive in rain, if you smell mold as time goes on, this is your problem. I believe mine was built missing some type of gasket in the seams as these TTs with a corrugated fronts have been around for years. Next TT will have a fiberglass cap for sure.
  • Silicone will degrade if on the exterior. Better to use one of the newer polymer sealers.
  • Never use silicone anything on an RV. Won't last and is a mess in the end. Polymer sealants like Dicor are the correct choice.
  • Silicone will work fine as long as it isn't subjected to UV.
    They use it underwater in pools and spas to seal parts.

    Unfortunately the spot you found the leak is very common with aluminum clad travel trailers.
  • A lot of misconceptions on these forums regarding silicone.

    I agree with not using it if you're talking using whatever comes off the shelf at the big box or Ace.

    Its a different story if you can lay your hands on some of this. Keystone uses this, or was using it, for all joints that did not involve roofing and its good stuff. Why don't most manufacturers use it? Because its expensive...thats why.

  • Ralph Cramden... you hit the nail on the head. I am in the residential home building business and we use dymonic sealants (trench) to seal older window frames (aluminum frames). It was easiest to describe it as silicone.

    Anyway, I don't plan on keeping this TT more than a year or two, we made a poor choice on our 3rd TT and we just have to live with it until then.

    It is well covered from a large RV pole barn that I built (18w x 40L), I am not worried about the sealant failing. If it seams to need some maintenance, that is easy enough to do. I use this dymonic on everything around my property, I am confident in its performance.

    Thanks all for your thoughts.
  • We bought our Prime time Avenger in 2014 to replace the 2007 Surveyor the was totaled in a storm. We have had many problems with this trailer including a window gasket installed upside down (expansion joint on top) allowing water to pour into the wall. but haven't had any problem like what you mention. But thanks for giving one more thing to worry about.
