I remember seeing one like that had bunks in the back that could fold up with that extra door on the side, think I spotted it at Watsons of Coffs, but no other details come to mind.
I have a 2013 pdf which has it. I think it went 2016 or early 2017
There was a Sterling the same setup as well. Sterling 21.65-2.
So at least 2013 for Starcraft
I found a old 2010 Sterling PDF so the Sterling been around for a while.
I know I saw a nice outback Sterling with fiberglass sides a while back..
