Restoring a Sunline
1. Repairing water damage on your Sunline.
There are several links in that section with good pics of a rotted floor being taken up showing the floor joists.
Hope this helps and good luck.
PS, if you can picture document your repair I can add your thread to that good list for others for future reference to help others. This topic comes up from time to time.
