42 RDB Frame Flex, It go us. Now what

I had identical indicators on our 2020 39FBB with the small separation of the wall and cap.

Like you I was still under warranty and was able to have the repairs covered by Vanleigh and the work was done at the Tishomingo service center.

This pic shows the separation on the passenger side. The link is another thread that shows pictures of the repair they carried out in Tishomingo.
