Greetings from the Florida Panhandle
Why Airstream would do that? Sometimes they just have to choose the lesser of two evils. When they first came out with the 25FB several years ago, the door was rear hinged and hit the awning arm. After the production of about a dozen units, they decided that this was wrong, and switched it around. Then it covered the kitchen window when full opened. Either way, there was a down side. In the case of the 25FB, I think that they opted for the front-hinged version so that there was not a suicide door situation where, if the door were ajar, it would be more likely to blow open while underway.
As far as changing your door, it could be done, but at great expense, as it would require a whole new door and door frame.
