I dont need a ladder, but I'm 6' tall also. I guess you could use a little stepping stool if you needed to. This is also a one person installation. Everytime we go camping my wife sets-up the inside while I get the trailer leveled and the awning up on the outside. There was a question as to what slid in the railing. In the hardware department of most lumber and parts stores you can find chain for sale
by the foot. Usually they have whats called rope chain and its simply woven braids of steel covered by a clear rubber coating. I bought 7 feet of this, folded the end of the canvas around it, and sewed it in with large twine. This then slides in to the rail and is ridged enough that it will not get stuck on the other end as long as the rail ends have been smoothed down. The canvas can still be folded for storage as well.
