They used the same molds for all classic 17B trailers. That would be from about 2005 to 2016 when they changed to the newer style trailer. It's expensive to change molds. New molds are $150,000 plus.
Not sure why your asking. I am 6' 1/2" and the ceiling height was no concern. The concern is the trailer width. With the dinette down the bed is 6'4" across. A little tight for sleeping. Also consider the doorway, I hit my head many times going in and out. Lots of room at the AC and Maxfan.
We had a 2007 Escape 17B for 4 years, sold, Escape has a new 19' waiting for pickup.
Edit, the earlier 17B had a window style AC unit above the fridge. I preferred that as they were quieter and way way cheaper to replace if need be.
