Who is using swivel wheel/Idaho Tote type carriers ?

From experience I can tell you my Kendon MC trailer tracks outside the 5er. I was parked along side parallel to a curb. I needed to turn around so I cranked the wheel hard to the left and started rolling four lanes plus a turn lane. As I was part way I looked back to see the MC trailer jump over the curb with the curb side tire.

Maybe it was the conditions but I was shocked to see the MC violently move side to side. I stopped down the road a bit and tightened up the straps!
