Main differences between what is called side air bags versus roll over air bags:

Side impact curtains stay inflated for only a second or two, while rollover curtains stay inflated for around 10-20 seconds depending on the type used.

True rollover curtains only have a rollover sensor. However, a side/rollover system has a rollover sensor, as well as side impact sensors.

On the H3, the rollover sensors is under the console, while the side impact sensors are in each front door.

As for prices, I have no idea.
