I don't remember where, and it's getting late for me, so I don't want to look it up, but I think, THINK, that there is a rule stating that the place the trailer attaches to has to be stationary or something.

And I would like to bring up the 4WD drive with the steering similar to a car, what's that called, by the way? I think it would definitely give us more control overall. Especially when compared to skid steering or something. One question that bothers me about it though, will the low coefficients of friction render this kind of steering just not worth the time input into designing and making the system?
