Thanks, and yeah, I may end up doing that. It was a fluid process, making changes as I went. Started out with the hinges on the inside and then flipped them; honestly don't remember why now.
Probably to hold the center in line when installed. Just a guess.
That will work just fine, though I would get rid of the hinges.
Without the hinge he would have to attach the middle ends to the trailer as there are only two stake stubs per side.
