when my ex-GF and I were driving from CA to MO, she was at the wheel when she lost control of my Explorer Sport, pulling a fairly short UHaul (and to be fair to her, she thought I was about to tickle her and flinched too much). The trailer didn't like that, and performed a few gradually increasing yaws until it spun us into a nice... 360? 640? I don't know. At highway speeds, we ended up on the center rail, facing traffic, trailer on it's side.

Thank God we did't flip - I had taken my belt off for a few minutes for some reason or other.

My point is, you don't want to experience it! And, FYI, it gets pricey hiring a tow truck for the car, and another for the trailer.
