A lot might depend on her usage. If she is social and enjoys sharing space, going above just a dinette for seating might mean a chair, or even a couch.
On the other hand, if there might be others that share a campout with her, beds might be important. Mobility issues might mean no overhead bed, or if she is agile she might like the compact Majestic 19. I met a lady that just loved hers and travelled with a group.
I would have to agree, the best decision might be to get her to come on here and ask questions herself. I have also seen some disasters where single women have purchased unwisely without good advice, and they deeply regret their decisions.
