Cab over Front Window Leaks

Do all cab over front windows leak? Can anything be done to prevent it?

When we bought our current unit (2005 Four Winds) a main consideration was no cab over front window. Now we are looking to move up (size & age)and still every pre-owned unit we look at with a cab over front window has water damage.

I have found a 2014 (new - left over)at my price point, but, it has a cab over front window. Should I pass on it, or is there a preventive measure?

Regards

  • I saw a somewhat similar post a few days ago where someone gave a good description of the front window. With it, you roast when its hot, freeze when its cold and get wet when it rains. That doesn't sound like something I'm looking for. How about you?
  • I would pass on it, its not a question if it will leak but when. Why look for future trouble, just read all the threads on here about the famous cab leaks and all the down time, frustration and money to repair them. Make sure you get a solid front cap with no windows to reduce these problems.
  • They do leak more often than not which is probley why front windows are rare or not available on better brands. If I bought a unit with a front window would remove and reinstall. Best of luck
  • I have a 1997 Yellowstone with a cab over window that I purchased 4 years ago. The front window has not leaked and has no signs of ever leaking. I have had other class C's with windows that leaked. What I did to stop the leaks and I also did this as a preventative measure to my current unit. I removed the metal inside trim around the window. (Many screws) I then caulked the open space between the window and the wood. Do not be stingy with the caulk you will use plenty. This is a pain to do because you will be working on your back most of the time. Many leaks occur because the opening for the window is cut too large. If you have cab over side windows, then I would do this for those also. Next check the black gasket on the outside of the window that it is tight to the glass, especially on the bottom of the window. If not, then a small amount of sealer can be used to seal the gasket to the window. Also many cab over leaks come from the molding on the roof where the cab over meets the roof.
