I did the 3 leaf progressive AAL. If I could do things over, I'd almost rather have the bumpers done and then do the suspension to make sure I'd be sitting level and riding nice. My coilovers are doing OK with the new bumper, but they're cranked kinda high. Not excessive, but the truck is still not QUITE level (though it's pretty damn close).
Heavier coils up front and a leaf pack built with the consideration of rear bumper/tire carrier/bed rack/tent would be ideal.
Still, I ain't complaining. I'm loving and using this truck more now than ever.
