Thanks. All are useful comments
However I would prefer to know in advance the balance point of the 3 wheeler, and then, as the trailer I'm asking for is not standard but will be manufactured for me, so I can change its specifications, tell the workshop where to place the axle. So I might have a really balanced set!
And avoid overloading the towing ball / bracket, which by the way has a maximum vertical weight / tolerance as per the manufacturer, the car's shock absorbers and the brakes.
Better having a balanced set since the beginning tan playing later with nose weights to re-balance!
