Focus HD Fat Bob 2013

Hi guys, I’ve got a TPV single-axle trailer. Question: has someone of you already determined the focus of ́ner Fat Bob. I’m about the adjustment of the front wheelbars because of the load on the drawbar so that I can properly balance the buck on the hanger. Before I try to find out where it is, someone can tell me about his experiences. Would be cool if someone has an info for me. Greetings and thanks Tommy
