I would contact Northwood and discuss this situation with them and see if you could take it to a dealer close to where you live and have them see about fixing it under warranty. Might be worth a try.
Another thing you might want to hit off them is sending you the new tray and install if your self if possible.
The reason I'm responding is I use to have an AF1140 and it was a good camper and hate to see anybody with a problem on the AF. In fact when I had my NL I bought the AF Fox Landing and installed it on the back of my 2012 NL.
