I always used ratchet straps hooked to frame of trailer, front and rear. I used 2 straps in rear, one on each side of axle housing. No brake line concern on mine. I used a single ratchet strap in front around K frame hooking to 2 points on front trailer frame. Not having seen your trailer frame I cannot say for sure what works for you. I never needed stake pockets or D rings. I would hook directly to frame if possible.
