IMO, you should practice backing the trailer.
I would not hang more than the listed max weight off of that hitch.
After reading the link you provided in the other thread, it is clear to me that the hitch is intended for use with light loads or only in straight line pulls - as a winch mount.
Many truck frames are boxed and the manuf's like to brag about that. A boxed frame can be built from thin steel sheet.
I'll bet that your truck also has crumple zones designed into it. It would be a real shame to kink or fold a frame.
Some manuf's offer snow plow packages to accommodate extra front end weight.
