im a little late probably, but i just found this thread lookin around at bumpers.
eagsc7 and rich, i dont think its the same bumper exactly, but the flatland 4x4 rear diy bumper has the same storage feature if thats what your lookin for. it looks a lot similar, maybe better imo, and has opt for a tire carrier. basically kevins stealth style rear, only you get to do all the work! ive got the plans for the front, rear and tank skid when i can get the time and $ to get it done (after my 1 and 4 year old kids graduate at the rate im goin!).
