wow
that would work good, but man alive it would beworth more than your truck lol
personaly i wouldent waste the money on dom (let alone stainless) in anything you dont have to trust you life to ie cage.
normal herw tubeing is fine for most worklike bumpers and sliders and whatnot.
get thicker tube if you want more strengh, way cheaper.
unless you want to make it indistrucable, Btw stainless is a bitch to cut, most likely really hard to bend, and unless you have stainless rods, or wire you welds wont be stainless
