2X20 Containers on a Slider

Hi guys, is there any rules or recommended advice on putting 2x20 loaded containers on a normal slider?? one driver has quoted that one box should not weight any more than 5t heavier than the other, how true is this?

Regards

Aaron

The sensible advice is not to stick 22 tonne on the rear end while you have only got 6 tonne over the pin
