This topic has been touched upon before, but my problem is slightly
different. I am using pfGetNodeBBox() on a particular vehicle model,
trying to get the visual bounding box, and using the extremities
for intersection testing and terrain clamping. However, the bounding
box seems to be slightly different than actual. That is, the vehicle
goes up a hill before it gets there! Can someone give me a quick hint?

Here is the hierarchy, if it makes any difference:
