As long as we have to share the roads with truckers (and I don't see that changing anytime soon), I feel much better having my family in something reasonably substantial and safe.

I share your discomfort with the number of transport trucks on the roadways, and it is most certainly a motivating factor for larger personal vehicles.
From a policy standpoint, I would suggest that moving a lot of truck traffic to rail (safer and more energy-efficient) would have any number of benefits, not only a reduction in environmental damage and infrastructure costs, but increased safety for passenger vehicles, and particularly for smaller vehicles.
FWIW, this is a problem here in Canada, as well. Driving between two major cities (the Toronto / Montreal corridor, for instance) the highway is filled with trucks all going from one city to the other, an enormous waste of energy, public resources and tax dollars. Again, this is policy-driven - as long as it is cheaper for companies to move goods on public roads (for which they pay only minimally) than it is for them to assume the true costs of moving goods by rail, they will chose the cheaper (to them) option.
At the end of the day, *someone* has to pay the cost of all the externalities. Currently it's the taxpayer / citizen who foots the bill, paying for more & wider roads, poorer air quality, more traffic congestion, high fatality rates in accidents involving commercial vehicles and concomitantly higher health care and insurance costs. We need to pass along a use-proportional portion of those costs to companies (who exist purely to make a profit, after all.)
A friend of mine bought a little wooden jigsaw puzzle at the dollar store the other day... Made In China. Can you imagine? Thanks to the various companies not having been charged the true cost of their actions (HR and environmental, energy, infrastructure etc.) it was cheaper for them to stamp these things out in Asia, truck them to a shipyard, ship them all the way across the Pacific to BC, put them on a truck, truck them across an entire continent and distribute them here, than it was to manufacture them locally. Little pieces of wood... pretty sure we still have some of that up here.
All of which is a *very* rambling way of saying... on an individual level, I don't take issue with anyone's purchase of a Hummer, or an Expedition or any other vehicle. We all have our reasons. On a macro level, we need to look at our energy use, the real costs of which we are only just beginning to feel.
