Bringing possessions across the border at a later date

[JaJo08 0]

My wife and I have now changed our plans for her move down here and have another question. The plan is to just drive down in her car with the two of us and what can fit in her car.

Her dad has now offered to tow down a Uhaul trailer at a later date with all her stuff in it. Probably within the next 2 months. I'm curious what needs to be done for this if anything at all? My understanding is that when my wife first lands at the border crossing that she can bring in all her goods and it's exempt from any duties, is this correct? If her dad brings them at a later date will they still be exempt? or is there a time period that they are still exempt? What do we need to give her dad to allow him to bring all her stuff down in the Uhaul? A declaration form and a note?

You need to give him a 3229 and a photo ocpy of her visa. She has ten years to bring all her stuff in
