I don't think the strength of the ring is the question......but the qulity of the weld holding it in place. I have lashing rings on all four corners of my truck. Stick welded in place for the long haul. Most any trailer place will have them for a resonable price. Magnum trailer(which means expensive)had them for 8.00 dollars.
While we are on the subject. Does anybody know where to find stainless steel D rings? I was looking for the one with the 3/4" bolt(I think they size them by this). Got mine for Lowes. I think that the stainless on black bumpers would look nice. That way it will look more normal when I put on my rocker guards with stainless bolts.
