Trailer: 2017 Escape 21, pulled by 2018 F150 EcoBoost
The molds for the 21 foot Escape were changed in July of 2016. We received the first trailer of the new style off the production line in September. (Our trailer delivery was delayed because of problems with U.S. customs)
The major changes were:
Sides are straighter. Gives the trailer a spacious feel.
Windows were changed to awning style
Door is a standard size and flat.
Powered awning with no legs
I'm sure there were more changes and other people will add to this list.
The classic 21 has a flat floor front to rear the newer one has a stepped up rear dinette. The door is wider to allow for a wider selection of refrigerators. Awnings have a recessed mounting on the shell.
