LOL-I was rollerblading there yesterday; how come I don't get to see that-and how did it not make the Spec??
In terms of helpful suggestions, the "hand at the bottom of the wheel" is a good one. There were lots of references about practicing in a parking lot etc. One of the most important things is to get a sense of how quickly your rig will respond. I've got 2 tow vehicles and it's quite different between them even with the same trailer on the back. When I'm with the family, it's the mini-van and I find it helpful to have the back hatch open for better visibility. Also, adjusting your mirrors downwards can get you a better view of the ramp edges, especially when your trailer is on the incline but your vehicle isn't that far back yet.
