I can answer that for you Rick.
You can tip one over at 5 MPH, its called positive and negative camber causing the centre of gravity to move significantly in the vehicle that the kinetic energy then works against the force of gravity holding it to the road.
As you enter the roundabout and steer to the left (So you can drive round it)the energy is sent to the drivers side of the vehicle, as it returns to the centre, the vehicle would then be turning to the right going round the roundabout and the kinetic energy would move further to the passenger side than it would of if the vehicle was going in a straight line, this then causes the vehicle to tip over.
Its like having a bucket of water, if you have it half full and move it side to side at the same speed the water will get higher and higher till it comes over the top.
The 5th wheel stops the driver feeling the effect till its too late because that will move with the load, the first thing you would know is its going over.

I bow to your superior knowledge, all I know is it went over, sickening feeling, Rick
