Class A with tag axle - beware of $1000. fine in AZ!

I like getting the info from the horse's mouth and sent an email to the AZ DOT. Typically, privately owned RV's are exempt.

If this turns out to be something they intend to prosecute, maybe FMCA can step in.

I do question how this works at the stations with an RV pump. The fuel is the same price as the car pumps, at least at the Pilot near Lake Havasu.
