My question involves search and seizure law in the State of: New Mexico

Hi, I stumbled into this question for some time now.
I know that in some cases, such as the border checkpoints, a warrant is not required for the Officer to perform a simple search in someone's vehicle (ie. take a look in the trunk), all they need is Probable Cause.
From what I've read, Suspicious Behavior from the part of the driver can give the Officer reasonable suspicion, and therefore probable cause to do an inspection of his car.

I'm trying to figure out if attitudes such as constant refusal to show some basic documents (ID, drivers license..) is enough for the Officer to have grounds to perform a simple inspection in the vehicle. Keeping in mind that this is an area where drug smuggling is rampant, and undocumented immigrants exist in large number.
Cases that deal with this specific situation would also be helpful.

Thanks in advance
