Utility trailer mod for toys

I was torn between using what I have already done and buying a weekender ladder rack and mounting to the trailer like you would mount it to a pickup truck. The advantage of the weekender ladder rack is that it is removable but I would have to spend $300. I decided to use what I have but make it safer by using floor flanges for the pipe and u-bolts drilled through the angle iron at the top rail.

Thanks for everyone's input. I'll have to post a picture once I get the bike and the kayak on the trailer.
