mine was a 2015. only RV I ever purchased new. The rubber roof failed and the sidewalls delaminated..
so I was pretty disappointed with it..
I was faced with taking a bath on it financially and trading it or letting it fall apart while I watched.
Lucky me, because it was the year after covid and RV prices were appreciating
and there was a timely brush fire and I decided not to move it
and see if Mother Nature would rule in my favor.
she did.
