well ill ask ya not to leave it down, even with diamond plate as a back, it looks stupid......... from my own experience. I have made soem brackets, that i found the palns for on here, Just do a serach for "Body Lift Bumper Brackets" or "bumper brackets". And mine i really cant tell are anyweaker, but the only thig i pull is our four wheelers. and 18ft boat, but thats all off the bumper. SOem might not suggest it, and i prolly do to, but hey its the only way for us, since i dont want a hitch....
PEACE
