Again, just my opinion, but 2x3 and .125" seems like overkill on strength and weight, not to mention possible clearance issues above and below the floor. Having it welded into/through the floor with the inner roll bar legs should make 2"x2"x.083" plenty strong. Then you can add any extra weight where you want to and where it will do the most good.
