the rubber on mine never gets damaged.. but there will be little divits in it for a short time after I put the doors back on. ... I did it this way last summer.. and all winter never had any wind whistles or water leaks... no doubt that some sort of support at the bottom or maybe a wooden rail with some rubber on it would protect them better.....

may be just as simple as a second set of hooks at the bottom of each door to take a good amount of the weight off of the window rubber.....

my neighbor has a spring scale... much like a fish scale, and I connected it from my pulley to my my top holder... I accounted for the weight of the top holder and measured total weight. Now granted, I had to keep it stable so I may be off a bit, but can't be by to much. I used the same scale for each door.
