Yes the Axis/Vegas models are identical for the given reasons.
It does make me wonder: how are the Axis/Vegas models treated by Thor? Are they built alongside the C's (Since they have an E-350 chassis) or are they built with the A's..
According to the plant tour page:

Axis/Vegas units are built by themselves in their own plant. Hmm.
