Brandon, are you still covered by the warranty? You might contact Heartland customer service and have them make note of it, so that you can get it into service when convenient for you, rather than disrupting your enjoyment of it in the middle of camping season.
That said, it may be happening because of the change in weather. We discovered a squeak in our living room, but once at the dealer 3 mo later, they could not recreate it. Seems it's a seasonal squeak! We just live with it. Ours appears in the cooler months.
