Being that the Rams have coil rear springs, it makes sense that it would sag with a light load as coils have less internal friction than leaf springs. That is why they usually ride better with light loads. A coil system normally will not have the axle wrap problem that the light duty leaf systems have either. For heavy loads, you can have different rated leaf springs and overloads while a straight wound coil is one rate. Will Ram use a progressive wound spring or overload bags? They have the air spring suspension but it sounds like they were more worried about ride quality than heavy hauling.
