I was always told twin rams were dangerous, this is the proof

i used to hate it when they leant over, seemed to be a case of jack it up, its either going over or it wont (but never if it was leaning my way!)
worked for emr on the artic tippers pickin the scrap cars up,they
were ok until you had to tip on dodgy ground they used to rock
like a kin saleboat
