Taking delivery of our 2013 Essex today. We chose the King Air floor tile with the 3 in square glass inserts. We went for a 25 mile test drive with the rep, then pulled in to the dealers campground and got set up for our first night, jacks down and leveled. To our surprise two of the glass inserts are cracked? Has anyone had this issue, dealer says no worries they will take care of it, I am concerned!! Do they really crack this easy, will they continue to break when replaced?
