Towing Inoperable Vehicle 4-wheels-down - Laws? Registration? Insurance?

Hi All,
I just cant seem to get a straight answer, or any help with where to
look for towing laws from any local authorities.

So here's my issue: I need to tow an inoperable vehicle from New
Mexico to Arizona. The vehicle does not run, but it is safe to tow 4-
wheels-down with a towbar and has all required items (lights, etc).
The insurance and registration/tags expired on the vehicle several
years ago. The truck that will tow the vehicle has current insurance,
registration/tags, etc.

Are there any NM/AZ laws that state I cannot tow my inoperable vehicle
since it does not have current insurance/registration?? Can anyone
point me to the specific law that states this?

Thanks,
.
