Not sure, but personal opinion, I think tying in both rear a-arms with this hitch strengthened the rear end, as well as bringing receiver up and avoiding the shin obstacle when not in use.
I would suggest not using a standard pin and clip to contain your HF carrier but use a shoulder bolt, the ground has a funny way of ejecting the clip and loosing everything, happened to me at Takeover last year, now it’s bolted in with a stainless shoulder screw and ny-lok nut, no more worries.
Wouldn’t want you to hit a rut, loose the pin and have your deer on the ground and no way to get it home.
