You'll have to test it as you go, it's not always obvious where best position is.

Put some weighing scales under the jockey wheel and lower the hitch to the same height as when on the car and play around to find the best load position.

You soon get to know what nose weight feels most stable.

If you are looking to buy a trailer see if you can get a stabilised hitch, they make a huge difference with caravans.
