New trailer. Where to weld the D rings?

I guess its a preference, I cross my cars straps on trailers and lines on boats in a slip, prevents the sideways movement. If you straight-line strap using this UHaul transporter, the webbing will rub on the deck.

I can GUARANTEE you that if one of those two fails, the other one will allow the load to shift sideways, and then the LOAD is LOOSE, left / right, and front to rear. Once the load comes loose front to rear, the FRONT straps are both loose and you have LOST that load.
