I have an Apex. A 2013 but a 288BHS. To date. It has given no problems. One hub did lose a seal and had to be replaced. But that is a axle thing, and they all use pretty much the same ones.
As for Coachmen. They have been around forever. Both the Apex, and coachmen are made by Coachmen, or more precise. Forest river. Not real sure about the floors. But should tell you on their website. Both do have AZDEL walls. That is GREAT. 50% lighter, 50% stronger, and has 50% higher R values, and will never rot.
