There is not definitive answer to your question. Every setup is different most trailers have different configurations.
Drivers can adapt to their configuration through cautious practice and varied situational maneuvers.
Even experienced haulers can screw-up sometimes.
I witnessed an experienced hauler just the other month who was moving a trailer for a friend, nominal fee. He had a lapse in judgement and out popped the cab rear window, dent, and $600 gouge / full body paint repair in the trailer front cap. ouch!

BTW: the general preferred pin placement for hauling is about 1>" forward of the drive axle center. Never behind except backing w/ a slider. Could cause adverse steering reactions.

Every additional 1" forward transfers an approx. % of pin weight to the steering axle. This would allow for modest handling and road character adjustments.
