I don't know all the difference the low pinion implies, but IIRC they're not
as strong as the high pinion D30. Are there other implications as well?
How much difference is there? Not that it really matters, this is going to
be a daily driver / Family vehicle.

I don't belive the LP Dana 30 is any weaker than the HP Dana 30. The only
difference is the pinion is lower, making it easier to damage or get caught
off road. It also increases the front driveline angle. None of this is an
issue if it's a family driver that won't be lifted or wheeled.
