Centre of gravity

[Big Jim]

Not yet , I picked up the trailer yesterday . . Today I will be chopping and welding , it needs to be narrowed by about 6" to fit between the camper legs . It is still standing on 3 legs and a piece of wood , so not sure if I can drop it on yet

Done. And I think it works,
I took 7" out of the centre of the axle and welded in three 2"x1" box section crossbars at the same height as the axle, so that takes a lot of the weight. The hitch has slotted holes so it was easy adjust the "A" to suit the new width. The motorised jockey struggles on grass/uneven ground. I have only moved it by about 5' and not tried to get it out of the gateway.
I think it will be more stable if strapped down and take the tyres up to max pressure
