I called around Portland, OR for glass replacement. Speedy Autoglass was one of the sites. They sent me to Gresham Glass in Gresham, OR. I removed the window and took it to their establishment. They made a pattern, tempered the glass and installed the window. Cost was $35.00. They said it would take 1.5 to 2 weeks which ended being 2 days.
I will install the window in the next day or so.
I now have to fill the new propane
tanks and clean up the trailer. I also had a new A/C unit to install.
Eventually I'll get the trailer usable again and then find time to do some camping.
