I went out to the RV today and this is what I found. It seems one of the main doors has cracked.. The other door up at the front is fine but the one in the back is not. Here's a pic. What could of mad...
My door has done the same thing, on a 2011 thor fourwinds, we are in the process of dealing with the door dealer. I was told that they do that all the time, but have not found anyone to support that. I found nothing else wrong just cracks that look just like yours only mine are on the inside of the door.
