Actually, it may be that many of the F-150 live a life of being lightly loaded, but I suspect that the reason people ( usually businesses ) spend the extra for the higher load rated vehicles is because they have work for them to do on a regular basis.Seems like trucks are priced really high (1) as a profit center for Detroit and (2) for dealers to be able to offer huge discounts. Detroit is going to be in real trouble if trucks and SUVs ever go out of fashion.
If I were being cynical, I'd suggest that not many trucks will ever haul a load of anything and very few 4X4s will ever get off the pavement. But this being the week-end, I won't be cynical.

With prices like that I can see insurance cost on all vehicles going up. If you hit something like that it is more expensive to get it repaired.
