Ok, back from our trip. Removed the daynight shades....couldn't find the screw on the ends so I just removed the valance. 6 easy to access screws and then I could get to the two end screws on the shade. Think I will mount the blind to the valance then mount the valance when I am done.
Purchased a restring kit from Camping World. Has enough string to do 5 small blinds and the instructions included are pretty good. I watched RVWithTito's video on restringing and that helped clarify some steps in the process. Always nice to see how its done before you start ;-).
Will let you know how it goes when I am done. This may take a few days with other projects in process.
