365 saq cracked caulking on king pin

I have some caulking cracking on my 2014 365 saq. The are of question is on both sides of the camper on the trim piece over the king pin. It is parallel to the ground and runs about 3 feet from the bottom of the from cap to where the body starts to curve down.
The caulk has cracked. My dealership added some caulk to the crack where the caulk had separated. It cracked again. You can see the trim/caulk move when you are unloading and loading the rv from the truck. The dealer says that the flexing is normal. Any input? I am going out tomorrow to take the old caulk off and apply new caulking the correct way.

That part should not be flexing. The pin box area should flex some, but not on that part of the wall.

I have a 13 saq that does the same thing but only on the drivers side. This has been happening since new. I called forest river many times and they say it's normal. This past winter when it was in for other work I paid my Rv dealer to remove the cover around the pin box and they found nothing. I will say what ever they did when putting it Back together has made it much better. I have logged 3000 miles since the repairs with no calking separating.

At the Goshen rally, the techs removed the vinyl strip and replaced the screws with larger, longer screws and that solved the problem on mine.

Friday I called the dealer and was told to put 3 inch metal screws into the trim around the overhang of the 5er and then recaulk. I put #10 3 inch metal screws in both sides and recaulked. My initial trial run shoes no movement or caulking cracking on the passenger side overhang. The driver side over hang still has some seperation/ cracking in the caulking when the 5er is attached to the truck. It's better than before. Any suggestions?? Should I just let it go and keep an eye on it to see if it gets worse? Take it to the dealer? I do have some squeaking when loading and unloading in the area. Any suggestions would be great. Going to disney for 10 days at thanksgiving and do to want any problems.
