Doesn't sound like anything major but none the less, things that shouldn't be there on a new trailer.
Our dealer has a CG on site that they want you to stay in when you take delivery (included in purchase and part of the PDI). We plan to stay and go through everything. They will fix anything the next day before taking it home.
Good luck and hope it all is fine.
