Since it's a relatively small amount of tubing you could use .120 wall 4130 and yield really high strength. Making those bends with .250 wall would not be fun unless you have access to some really good equipment. Like previously said, it's pretty pointless to use tubing that thick. 2"x.120 is standard for most stuff on trophy trucks and they see a tremendous amount of abuse.
