RV Repair: installing double pane windows in trailer, double pane windows, 5th wheel trailer

Question
I will soon be buying a used 5th wheel trailer. Few seem to be equipped with dual pane windows. How difficult would it be for me to install double pane windows in a 2, to 3 year old, Jayco trailer? I have worked with tools all of my 76 and counting years.

Answer
Hi Alan. This is not a hard job if you have a buddy. Remove window screws from the inside. reinstall with tacky tape on the outside edge. Silicone the top edge. When you order the new windows measure the outside edges. Try to use the same window brand so your radius match. Good Luck.
