I installed the ICONs on option 2 about two weeks ago. With an empty bed, they gave me a full 2.75" of height increase over stock (my stock leafs had flattened a bit; I was sitting at 41.25" empty). Now I'm at a hair over 44". I have the RPG adjustable collars in the front, in the middle slot right now. Rake is ridiculous -- I knew it would be, but I have two long towing trips coming up in the next month (both 5+ hours each way), so I'm going to see how much they settle. After those trips, I'll very likely go to option 1 on the ICONs. I will likely raise the front up just a bit, as I don't like rake and don't typically tow.
