Great video! I installed a Bend Pak HD-9 XW three years ago. I like that at full height the runways are about 7' off the ground so that I don't bang my head.
It took me two weeks to get mine up and running since it was just me doing it. The instructions are good. Yes, one single person can do the install.
I have since added the floor dollies to move it if needed and the jack tray.
It has worked faultlessly. I adjusted the cables for the first time this fall. The instructions say annual but I found that it was not needed. I do lube once a year.
