compartment latch came apart.

Today while I was starting to get our Aria ready to use for the summer, I could not open the compartment for the electric cord. Luckily it was that compartment and I was able to get under the camper back by the engine and get a small vice grips on the back of the screws holding the latch loop. Any other compartment I don't know what I would have done. Anyway after getting the door open and removing the latch mechanism I found that the pivot screw had backed out, to the outside paddle did nothing. These pivot screws are not shoulder screws, and are supposed to be held in place by a lock washer. But, if you tighten them up enough for the lock washer to work, the cam will not pivot. And since the lock washer does not hold the screw, it rotates when the door is opened. So this one backed out. I pulled all of the compartment latches removed the screws and put lock-tight on them. Hopefully this will keep them from rotating in the future. I also do not know which models may use this style latch.

Did the other latches have lockwashers?
I looked at mine and it looks the there are no lockwasher on them but the screws have a shoulder and are just long enough to bottom out in the hole and leaving the cam loose enough to pivot

On my 2017 Miramar I had the same problem. I took some of the latches apart, lubed, reassembled, etc. My conclusion: These are poorly made latches. Notice the "made in China", I imagine Thor wishes they had stayed with US made latches.

I had several of my latches replaced under the initial warranty. It may be there was a bad run or a bad batch of these. Yes, they can be fixed but you gott'a play with them. Ugh.

All had lockwashers, no shoulders, would have been better if they did.
