True, I see what you're saying. If/when I make these to sell I will add more mounting holes just to cover my ass. 6 per side. I could also make the rails solid with a 2" x 6" slot cut out of each one to weld onto the frame (for added welding area) and then bolt the ends of the welded-on mounts onto the bumper. I guess it's just preference with that idea though.
