I bought D rings for my trailer, but didn't install yet. I want STake pocket D rings instead. Currently have chains around the corner stakes and I hook to the chains.
I used the chains on the stakes years ago, it just sucked balls, and I put regular D rings on my trailer, not good, my trailer has a wood deck, they rotted the wood out, after about 10 years.
Stake pocket D rings are a win, with heavy clasp straps on all corners, or a chain on the rear, with two straps up front, using the short axle straps.
