What's up with this? Seems like an unnecessary limitation, maybe something to do with the magnet hold-open interfering with the passenger side slider?
I recall trying to load something in my friend's E-150, but there wasn't enough width with the rear doors at 180 degrees. Fortunately, there is a manual release that allowed the doors to swing all the way open for loading. Hope there is something similar on the Transit. A minor issue, to be sure.
