The house itself is pretty straightforward; each section has a connector that joins it to the electrical system, and you run power to the panel as you would a regular house, only from a pedestal you set. The PoCo connects to the pedestal.
Now, the pedestal is where it can get tricky. The PoCo will likely want the trench (for UG feed) a good 5 ft. deep. You will need a ground rod, and make your bond in your section- not the PoCo pull section.
In practice, I suppose that the house itself ought to have a ground rod as well; though I'm not sure I've ever seen one!
