Recessed D-Rings installed. Due to the narrowness of the cross members, hole pattern of the backer plates and size of the bolts I did not use the cross members or frame. I do however plan to fabricate larger backer plates.
After much research I decided against E-track due to a lower total working strength, higher costs, trip hazard concern and the need to fabricate a backer plate which would further increase costs and installation time. I have some E-track sections that came with the trailer and may experiment with them in the future if I can figure out how to eliminate the tripping concern. A family member has impaired vision and would not see the raised track.
Thanks for your feedback.
