So I have 6112/5160 sitting waiting to go on. Has the Icon AAL. Should I just grab the Icon RXT now? Was planning on slipping in the factory overload to hit 2". RXT probably stage 2. 6112 with be at max 6/5 setting. Empty bed. Any other recommendations. Wanted to see what was available. Really need this done. Weight causes rub. Then I really can't pick up fat chicks.
