Officially, and to avoid any future litigation

it is the recommendation of Stovebolt.com that you *not* pull *anything* from a bumper-mounted hitch.
FWIW and speaking of, here's a little something I loaded and moved on a tag-along trailer Monday. The trailer is attached, via a hitch, to the frame. Not to the bumper

There are sometimes when a tag-along trailer is preferable to a 5th wheel.
Putting your one-lunger in the back of the truck may be less hassle all around.
It will be a good look!
