The import duty for automobile or SUV is very high - 45 - 60%, whereas for a pickup truck is 15-30% (I haven't been able to make out which.

Is there high import duty on a stove, refrigerator, large screen TV, etc.? We plan to drive down from Brownsville, TX when we move (if we can settle all the stuff with Mexico!)

You might want to take a look at the following website. It answers some of your questions.
