Picking up a truck out of state

I've seen some threads that talk about the same topic, however..

This is my first truck as a new O/O.

I am from California, picking up a truck in Ohio. I have insurance (48 states), a DOT #, MC#, IFTA is not set up yet due to EIN mix up at the IRS, but is being corrected. Got the Keeptrucking ELD, so I can log accordingly.

Only thing that concerns me is bringing the truck back from Ohio to California without stopping at Port of Entries and no IFTA sticker (if applicable).

Do I still need a trip permit for this..trip? I plan on taking the i70 west to the i15 south the whole way, so most states traveled thru don't need permits (correct?).
