The "real" load is way more than 114lbs - more like 400 lbs. The G4s had full-sized spares, bikes, kayaks, and other gear up there during some interesting off-roading. Rack loads are rated primarily by the attachment points to the vehicle - in this case, 10 M8s for the entire rack.
BUT, the Expedition rack is miserably weak compared to any other rack I've had.

It can't really bear much weight as point-loads - do NOT go walking around on it without a sturdy rack floor - at least 2.5mm alum sheet or that chicken coop flooring.
Also, be careful using the upper bar with rachet ties or people hanging on it as counterweight.
It does look cool though....
