So, what should I do while waiting for the axle to arrive?  I decided to replace some cloudy old plexiglass windows and seal some leaks.

One of the previous owners of the trailer decided to replace both the front and rear windows with plexiglass.  Given that this trailer does not have a rock guard over the front window, I can understand why he decided to use plexiglass.  But, now many years later, the plexiglass had become opaque, had warped, and the tape and caulk holding the windows into their frames was coming loose.  I decided to replace them with tempered glass so that they would be stronger than regular glass and so that if they did break for some reason, there would be less risk of injury.  I measured the size of the windows and ordered the tempered glass from my local window shop.  I also ordered butyl tape and plastic window glazing from Vintage Trailer Supply.  And I ordered Acryl-R sealant from Airstream.  When all the supplies came in, we were ready to perform the replacements.

To remove the window you simply remove the arm that allows you to roll the window in and out and then remove a single screw that hold the window frame in its guide track.  Once removed we either pulled out the plexiglass or broke the existing window to remove it.  Then we spent considerable time removing the sticky caulk that the previous owner had used to seal the window.  Once removed we placed the butyl tape in the recess which holds the glass, laid the glass in place over the butyle tape, and then installed the plastic window glazing to hold the window in place and shed water.

Here is a picture of the window replacement pro installing the new tempered glass.

Once the glass was installed we slid the frame back into the track, locked it in place with the screw, reinstalled the extension arm, and then sealed all around the window frame with Sikaflex 441 in the large gaps and Acryl-R in the small gaps and seams.

Oh it looks soooo much better.  Now we can see through the front window, through the trailer, all the way through the rear window.  I can see anyone who might be tail-gaiting.

Now, how much longer until that axle arrives? …
