I haven´t done that route myself, but here you can probably contact people, who have. But I still think that your question might simply be too large to give really good answers. My advice would be to do some research first, and then ask about some more specific things, that you come across.
What comes to shipping across the oceans, it might be cheapest by sea, and advantage comes bigger as distance increases... but still it is often worth it to also find out about airfreight. It has its clear upsides: speed, the length of possible delays (hours or 1-2 days vs. several weeks)... and in seafreight, more often than not, you end up paying considerably at the receiving end, the sums being very hard to know exactly beforehand. You also need to factor in the time, that your shipment takes to sail by sea. If you´re in the middle of your trip, where you´re gonna spend that time, and how much do you spend daily, when waiting for your vehicle to arrive (moving around is also more expensive, when you don´t have your own wheels beneath you). So keep in mind, that this can also become costly, especially in places like Europe or North America. If price difference is not huge, I´d usually lean towards airfreight.
