The telescoping ladder mentioned gets a hardy thumbs up! I use mine all the time as I am too "wide" to get up the ladder mounted on the back. There is probably a one foot wide person out there but he ain't me. Ditto on the way the steps come down when retracting... pay attention to where pinkies are when retracting!
