GVWR GCWR Payload question for commercial towing

Hey guys, hoping someone can help. I have been doing my best for the better part of the last 6 months to figure out what I can legally tow. Considering from both commercial and non-commercial perspectives. (Mini-ex is for my own use on my own property, but I also have folks ask me to do work for them from time to time and I've just said no so far).

I am trying to pull my 10,810lb Mini-Excavator and have narrowed things down to 2 possible setups for my 2019 Ram 2500 CC LB CTD (with a 2095lb payload according to the sticker):

Setup 1: (This works I believe, but I live off a main street with a pretty decent slope I have to back down that with the long bed makes it a bit of a challenge.)
- Bumper pull tilt 16k trailer to stay under CDL requirement
- with proper placement, the ex plus trailer weight should be around 1480 lbs for 10% tongue weight. I would likely run this between 1500-1600lbs.
== this would make:
-- trailer plus ex, 14810 lbs roughly, give or take some attachments.
-- payload minus myself, a full tank of gas, and tools should still leave a few pounds 2095 - 280 (me) - 233 (7*33 for full tank of gas) == 1582lbs remaining for tongue weight

Setup 2:
- Gooseneck 16k plain equipment trailer, raw weight 3800lbs
- tongue weight here needs to be around 13% according to the minimums I have found online. I really don't understand why this is higher than a bumper pull when it balances the load across the axles. Does anybody run at 10% ? Is this dangerous, or is it a matter that you _can_ put more weight on the tongue so people raise the minimum?
- ok anyway, 13% of (14610 combined ex plus trailer weight) equals 1899.30
-> this puts me over my GVWR
-> but not my GAWR,
-> and not my GCWR
-> and not if you separate the units, truck would be under, trailer with ex would be under.
== would this mean:
- would they issue an overweight ticket as a commercial vehicle because the tow unit is over gvwr when combined with the trailer even though everything else is under?
- can anyone explain _why_ a gooseneck trailer requires more tongue weight when its splitting the load more evenly across the axles, instead of pushing down on the back of the bumper like a skateboard? Everyway I think about this it should be the opposite.

The laws are just really confusing, and the physics of why a gooseneck requires more tongue weight than a bumper pull just doesn't make any sense to me. Any help would be really appreciated!
 
GAWR matters payload does not. You do not need a minimum tongue weight with a GN you can balance the load on the tandem axles if they have enough capacity and it still be perfectly safe
 
The higher the tongue/pin weight percentage the more stable the trailer tows, this is why a GN or 5er typically tows better than a bumper pull.

10% on most trailers is getting into the unstable range, 15% is stable, 20-25% is very stable.

GN trailers run more pin weight because it’s a much more stable trailer, and because they can. GN hitches can carry a heavier load much easier as it’s vertical onto the frame, and they don’t reduce tow vehicle front axle weight like a bumper pull trailer does.

GVWR is generally meaningless for weight laws, but be sure to check your local statues.
