Smuggler companions?

Smugglers get 6 companions, you get your first companion around level 8, your 2nd comes with your ship around level 16, third comes on Tatooine around level 26, fourth comes on Taris, fifth comes on Hoth, and your final companion will come on Bel Savis.

I played a bounty hunter myself, but I'm assuming the interval of companion introduction will be similar.

Sorry looks like smugglers get a companion on Nar Shadaa instead of Tatooine.

You'll meet your first companion pretty early on as a smuggler during the ord mantel storyline. You'll get your wookie after the 2nd planet. But basically each class will get there companions at different times based on the story.
