Typically, USBs are wired for 12v (save for any USB charging ports wired to be built into a 120v plug) and don't need inverter (or shore power).
I think you can pretty much take this to the bank, but your mileage MAY vary (people are reporting wiring differences even in same model/same year/same equipped trailers), so make sure to check!
Hope this helps.
