Seen this a lot over the years. As a RV model or line gets a good reputation and / or becomes popular, the manufacturer has trouble keeping up with demand. They add on new workers, extra shifts and quality begins to suffer. One shift ends and the next begins and if the communications between shifts is bad, stuff gets missed.
The two faucets in our last RV had not been tightened down to the sinks. We had missing and loose trim pieces...overall there were about 30 quality issues. The factory was close by so we took it there to have everything fixed. At the time they were the only manufacturer with multiple slideouts. The product line became real popular really fast....
