generally, if it's a truck, it'll get used like one and a MII has NO PLACE under a truck.
BTW, you can screw up a MII install,too.
kinda depends on what the end result is gonna be used for...
if bucks aren't an object, get a heidts superide.
upgrade the coilover springs to about 550-600 lbs and forget it.
i've seen them take a beating that NO MII would hold up to.
