OK, trucks (which is what SUV's reallly are) roll more easily than cars. You cannot criticise the engineers for that however, due to the necessity of an increased ride height and taller greenhouse the center of cravity is necessarily higher. Anyone who does not drive a truck with that in mind deserves to have a rollover acident. Explorers, Tahoes, Jimmys, Expecitions and the like are not built for maneuverability (sp?) at 80+ mph, which is the speed at which I see many of them traveling on the turnpikes. You cannot blame the engineers for the stupidity of the end user, that would be like me blaming myself when my little sister screws up the computer, not my fault that she has no idea how to use it properly. My only beef with trucks is when single people buy Suburbans and Excursions, or even Explorers and Jimmys. The things only get around 20 mpg and are perfect examples of conspicuous consumption. When my father bought his first Explorer in 1994 (a used 1991) he did so because he was going to be hauling a lot a demo and cutaway semi parts for a new job (regional sales rep). The rear shocks on that truck had a life expectancy of ~50,000 miles, half of normal, because he was actually using the truck as it was intended, hauling heavy items long distances. The same is holding true for the 1998 Explorer he bought new last year. The first set of tires (the recalled Firestones) lasted him 80,000 miles (yes he put 80,000 miles on a truck in about 1.5 years) and the rear shocks have been changed once already. If you need a truck, buy a truck. Don't treat a truck like a car, they aren't the same and you cannot blame the engineers for end user stupidity.
