That is a good idea Charlie! The biggest problem I have is also the smallest...even on an 8' ladder, at 5'1" , I can't get above the unit high enough to do anything! Now if I had someone holding the ladder I would be okay, but I am doing this alone... Twenty years ago I was 14' up on an extension ladder when it slipped, don't to try that again!
