Yes, I was a little confused at first also.
For a 2720, the 20' is from the rear bumper to the front of the hitch and the 27' is the total length opened.
I have a 2720 purchased new last Fall listed on this site, including details and photos.
It has the swing hitch and we fit it in our 19' garage, because it shortens to 18'

We replaced it with a 2720SL.
I have a cousin who lives in Cary. It's only about 4 hours from here.
Good luck with your decision!
