Wide is the way to go, narrow ballasts do next to nothing when your about to cock a leg . The narrow ones in the center of the 3pl are dead in line with the tilt pin on the front axle . As you can imagine, they will offer no resistance to a roll over . If you can make one as wide as the rear wheels, you are much better off .

Hold on there pardner (mate?)!
Actually, the ONLY way a wide weight can prevent tipping is if its so wide it extends out past the downhill wheels like an outrigger.
You're forgetting about the equal amount of weight on the down side,,,,, helping you to tip.
In reality it makes no difference left and right, it's the "center of gravity".
On your counterweight, I notice it's down low, even below the axle....now THAT is significant.
Yours probably works better than most others
because its center of gravity is LOW, not because it's wide.
I'm using a barrel, like MechanicalGuy (above), where the center of gravity is at the center of the barrel (about 2 feet high).
It would actually be better to lay the barrel on its side, the CG would be about a foot lower.
To drive on a side-slope PEJ5 should add weight (if needed) as low as feasible.
I have a piece of 300x450 hollow RHS filled with concrete, it is fitted with a cutting edge on the front, for grading the driveway and has a towbar at the rear .
And this too.
You can actually USE it for grading.
Cool.
