Is this normal since this is an Suv? or is this a sign of an alignment problem which is made worse in the wind? I always assumed even though it sits higher than a car which makes it more vunerable to wind and less aerodynamic that the added weight of the vehicle would make it even more stable at highway speeds in the wind.
