[Longhorn Man]

If your bumper is worth having, you'll probably want to remove it. I damaged it on both of my trucks with that tow bar.
That looks like the same model as my old bar. When you bolt the brackets on the frame, you'll probably have to spread the bar a tad.
I always removed the drive shaft. Just unbolt it from the rear axle and strap it up out of the way. This way you don't drain the tranny. If it is a stick shift, just pop it in neutral, but you can damage an automatic by doing that.
These are the only two pics I can find.

If you have never used a tow bar, I highly recomend a large parking lot to learn in before hittin the freeway. It's plenty safe, just feels funny and the lack of brakes on that 2 ton trailer takes some getting used to.
