Hmmm.... Received my 2014 340RK back from the dealer about 1 1/2 weeks ago. They had it since thanksgiving. For the most part everything that I specified to be fixed was. Took it out for 4 nights and was just putting it back away and noticed this bump under the middle of my bedroom slide. Looks very similar to the pics posted above. Also noticed that it looks like there has already been a stress relief cut below the front corner of that slide like was mentioned as well. Guess it will be making a trip to the dealer tomorrow.
