This is because the rear end does not extend as far from the rear wheels as the front does, and it's tapered to boot. You could probably even make the trailer longer if you keep the same angle.
In short, don't worry about it, as the trailer makes a smaller turning circle than your front bumper (by about 21"). 
If you were parallel parked next to a wall (or telephone pole, etc) and turned full lock to get out, you'd need the side of your truck to be at least ~8.5" away from the wall for your trailer to clear. Even factoring in the curved plan view of the average automobile (which in effect reduces the bumper's swing), I'd say that's pretty good. |
I'll assume your math is correct. It's nice to have the peace of mind (I would test it out to verify). If I was putting on a decent sized boat tail, I would do the same analysis.
I looked into a similar thing when designing a trailer. I didn't want it to be a problem when towing. I found through analysis (powerpoint, it's what I have) that it was not a problem, and that it would track nearly within the track of my car on the inside, and well within on the outside. I verified this by doing a couple real tight 360 degree turns on fresh snow.
