Entry door comes open going down the road
I have a 2015 Rockwood Signature ultralight model # 8244WS. I recently started having problems with the door coming open going down the road. The first time I thought I just didn't get it closed, so I closed it again locked door handle and deadbolt. Thirty miles later I stopped and found door open again with both locks still locked. This happened two more times, until I put a bungee cord across it to keep it closed. It even came open with bungee cord on it. The last 200 miles home I put bungee cord supper tight and it stayed closed. I have no stress cracks on inside or outside. Door locks go into Striker plate 3/8 of an inch on door latch and a 1/2 inch on deadbolt. The margin around the door seems to be pretty even. I called Forestriver was promised a call back but no call as of yet. Does anyone have any ideas of the cause of the door coming open. I haven't inspected the frame due to the underbelly cover is a son of a gun to get down. With no cracks inside or outside, I don't think it is a frame issue anyway. I am at a total loss on this one.
