Getting ANYTHING by mail, don't give a **** if it comes from SAT or Secretaria Gobernacion is EXAMINED at vehicle checkpoints. I just e-mail chatted with a (stranger) who complained bitterly he had paid for and received a 180-day permit for his F-450 while home in Colorado. Entered at Cd Juarez then was pulled over to the side at the checkpoint. Camper or no camper the Aduanero told him, his permit was incorrect and he wasn't going to let him through. He headed to Nogales and was refused there. That Aduanero told him even a 10-year permitted camper pickup would have been stopped.
People who claim that they just got a permit online should be taken with a grain of pepper. People who get a permit online THEN report from inside Mexico are the folks to pay attention to.
Lots of ADUANEROS go by-the-book AS THEY SEE IT. When I by medical am forced to exit Mexico and re-enter, I always keep this in mind.
The only way Aduana retracts stupid regulations is when it impacts wealthy and powerful Mexicans to the point where they threaten the SAT jefes with a 1 mile straight ahead stroll on a half-mile dock. Income from overland tourism is but a splinter in the great tree of total tourism revenue. It's sad. It's maddening. It's Mexico
