Hi
I have a manual appliance dolly at 66 inches and I got recently a 60 inch escalera electric one. I have a landing on my porch going into the house. I can turn the 60 inch escalera pretty easily but the 66 inch manual appliance dolly is a bit of a challenge to spin around. I find I'm not so good going down stairs yet with the escalera, I still use a my manual if I have help over, but the escalera is the cats ass for going up stairs, makes it extremely simple. I'll get the hang of going down eventually. LOL. As SealClubber mentioned contact Larry, I got mine through him and he was extremely helpful. Hope this helps.
