Some folks with other model coaches found that the door for the furnace is the issue if it has the louvered cutouts. Supposedly Thor is aware of the issue and will replace the door.
Since you do not specify the model or year of your Challenger I can't say whether or not you have that particular door. My 2015 37ND has the louvered door but it has not yet been a problem. It has been raining quite a bit the past few days so I may go out tomorrow and pull the door and look around.
