Yep, it's cracked. Inspect all welds for similar cracking. Then find a good aluminum welding shop to fix them.

What year and model Camplite?

His profile lists a 2016 16TBS. Probably a Thor unit.

It is a 2016 16TBS  with twin axles,  probably one of  the last twins  made.

Yup, same thing I saw on my 21RBS, it's seems to be common.

Like mentioned, just get a good frame shop that can do aluminum and get them to touch it up.
