The pictures didn't come through the first time.

The measurement of the king pin position forward of the rea axle would also be required.

Last year's numbers on a CAT scale (Certified Automated Truck) with front truck wheels same location each time.
Steering ax 4360 4460
Drive Ax 3280 5420
Trailer Ax 0 9640
Gross lbs 7640 19520

Pin/hitch plate installed according to instructions and appears over the axle or slight forward 1 or 2 "
I believe all within vehicle specifications.
What affect does this have? Any published info that a nonexpert could understand?
What about the pin and hitch movement?

According to my calculations you have an estimated pin weight of 2240 with your hitch centered almost directly over the drive axle. This theory is supported by the mere 100 being loaded on to the front axle. Total truck weight is 9880, in my opinion under laden.
A slider hitch may help throw more weight forward and prevent the rear axle being a pivot point. You can also afford to load the pin more. I hope this makes sense to you. Good luck

I have been towing the last 5 years with a Mor Ryde pin box...no issues and very little, if any "chucking".
