Why do these vehicles come with so much rake? I can understand rake on half-tons and SUV's withOUT self-levelling since you want to allow for some suspension sag under a full bed load or tongue weight. But with self-levelling you'd think they could come more level from the factory.. looks so much better. So to level out the rake somewhat what are the best options? Would prefer to drop the rear a say 1-1.5" rather than raise the front. Is there a way to fool the auto-leveller into making that happen without need for new springs? To be clear I do not want to lower the whole vehicle, don't want a slammed look, just flatten it out to a bit of rake. And I certainly do not want to compromise ride quality or towing ability.
