I like those d-rings on the outside of the frame. On the trailer I just bought yesterday the d-rings are welded to the deck, as the PO used wheel straps to hold his open wheel racer down. But for all of my uses, I'd have to run over them when loading a vehicle, and while I'm sure I could do that w/o a problem, it just doesn't seem right to me for some reason, so I'll cut them off and either move them, or replace them with new.
Nice looking trailer, by the way!
