Thanks for the input, guys. I do have ski glides on my trailer so I'm not too worried about that. What I meant was the edge of the trailer (it's a tilt) that contacts the ground when in the loading/unloading position. It sounds like the dolly trick would work on concrete, but what about on snow? I heard of one guy laying down a length of PVC pipe alongside (parallel) to the edge of the trailer and just driving up and over.
As far as the steering issue, I don't know exactly what was meant but what Pete describes sounds accurate to me. In fairness to ST's, it sounded as if most of the guys who were concerned about it had not actually experienced it, but read or heard it about it somewhere.
