Great looking rig. I am about to install the rough country 4" lift as well and will later order the front longarm upgrade from IRO. I have a set of their sliders. Let us know how the rear bumper turns out, I was going to order both front and rear. I hope to make them out of aluminium.
I've been wanting to build a set of modified Flat land bumpers out of aluminum for a bit now. I want to make them flush with the BW flares since I can't stand the way most bumpers look with these flares. I emailed Flatland and they said they would modify the plans to whatever width I gave them for double the regular price of there plans.
