Thanks for the extra pic's AHuey, that really is a great setup. Mine came in the other day, I put one of my bikes on it to size it up, I really dislike the center tiedown points, but that will be fixed once I copy your setup. Also kind-a disappointed in the length, I was hoping it would be a bit longer so I could make more use of it with some of my larger bikes. But I'm sure I can get a longer rail welded up soon, I just need the extra two receiver hitch's done ASAP, as I'm off on a trip in a week.
One thing you may want to invest in, is a fork brace for towing. See the orange + shaped item between my front wheel and fender, with that, you can tie town the bike very securely and not worry about pooping a fork seal because you've pulled it down too far.
But the backup cam is located perfectly so I can keep an eye on it while driving.
