Eric -yeah still not sure on what color. Was thinking of maybe even a Orange.
First off, nice trailer and at a great price. Not that I don't like the color but as a owner of a orange trailer I wish mine was black. I loved the color when it was new but now that it has been used and abused the orange it imposible to match. It was painted Kubota orange and was super sharp for a while though.
I added about $1k of chicken lights to mine so night time backing isn't a problem. If mine gets hit it won't be from lack of marker lights.
You mentioned your hubs, mine has hub caps that can be greased like what boat trailers have. So far I like them very well.
I don't think you'll need to load your tractor backwards. The beauty of having a bigger trailer that you have plenty of room to move the tractor around to find the sweet spot.
