This might help. In the same article where they posted the FAQs, they also posted an updated "Designers Commentary." This item is the very first question:

(Hopefully that link works)

Anyway, it says:

"Core Rules Questions:
Q. If a Vehicle model has a base, but it is itself larger than the base (such as a Stormraven Gunship), what do I measure to – the base or the hull of the vehicle?
A. Unless such a model’s datasheet has an ability saying otherwise, you measure to and from the model’s base."
