NEVERMIND!!!
apparently the steam comment compression algorithm is going to be uncooperative
see what it did to my nice neat visual aid !? 😡🤦‍♂️🤦‍♂️🤦‍♂️🤦‍♂️
to the steam dev. group:
Yes I know the comments section ain't exactly microsoft paint, but really guys? REALLY???🤦‍♂️look what your compression algorithm did to my diagram👇👎 ...not impressed (😕+😠)
(o` n 'o)

Glad you're enjoying it! Unfortunately, I've tried several times in the past to mod in my own models and, well... the MudRunner mod editor is really not very good, and uses a convoluted process involving a specific way to configure a model in a file format that has been deprecated since at least 2014, so I'm basically limited to messing around with the existing in-game models, which I can't cut parts off of since they're not in a readable format outside of the game. In short, the chance that I'll be modding in any additional outriggers is pretty much nil, unfortunately. Great idea though!

I'm not entirely sure what you're meaning in the first diagram, and I'm not 100% certain that it showed up as you intended. Could you clarify where you want a trailer hitch to be?

it's also proving useful for maneuvering cart type trailers around while performing sharp U-turns
suggested options are as follows:

suggestion one
\ /
0 0
the asterisk [ * ] represents the trailer-hitch point
0 0
/ * \
suggestion two
| <<--,
0 0 |
--- --- <-+-------- the outriggers that D 538 natively comes with
0 0 \
/ * \ <<----`------ outriggers that you would mod in (attached to bumpers)

OH dUUUDDDe that mobile winch point is going to be SOO overpowered
I LOVE it!
I can already see it coming in SUPER clutch for positioning the military-grade deployable vehicular bridges of another mod, not to mention boats and other small vehicles or trailers like the scout cart or even moving (without lifting) larger ones (I just tested this out on the garage trailer AND IT WORKS😃😲 *kinda* albeit with understandably limited success) 🤷‍♂️

one caveat: I'm not saying I'm an expert on mobile cranes, but I think they usually have four outriggers to completely lift the load off the wheels as well as for maximum foundational rigidity.

for the sake of space / character count, I have chunked the visual diagrams into their own separate comment
for suggested options, see my other comment
you might even say it might come in - "handy"... ...eh? eh? *chirping crickets*🤦‍♂️
