George I bet you moved back because of the "other" metal flange on top. A reasonable way to make your tiedowns very very strong is to add a plate on the bottom (with 4 holes). Drill 2 more holes ahead and add bolts that go thru the steel flange(s?). Use Self-locking nuts so its secure without having to squeeze down hard on the upper flange. Even a thin plate like 10ga, or 1/8" is very strong in this application.
The pics I posted are not of my trailer but from Etrailers website.
I don't have any tie downs mounted in my trailers wood floor. My tie down points are all to the frame of the trailers. The only thing I have mounted through the wood deck is a winch and only the back two holes. The front winch mount holes go through the frame. On the top and bottom side I installed 1/4" flat plate on all 4 grade 8 mount bolts. I do have a D-ring in the center of the trailer bolted through the wood deck but that is only to hold the winch cable hook when not in use and not a tie down point.
