Check the VIN, looking at your truck (nice rig, just got a 6.6 F700 myself) I suspect it may have been sold as an incomplete vehicle (cab and chassis). I have the reverse problem, mine was tagged 28,000 and I didn't want the class B hassle.
I found this: 01-22-N11B-3972.pdf It is a note from Ford to the NTSB saying that for incomplete vehicles, whoever completes the vehicle gets to decide what the GVRW actually is.
You can buy yourself some hundreds of pounds of additional capacity just changing all your wheels to aluminum.
Oh, what's your axle ratio and what sort of mileage are you getting? Mine was a crane truck with a final ratio of 5.6, I've been getting about 9.5MPG
FWIW, I bey your truck has a plastic radiator and it's not the mileage but the years on those. Micro-fractures on the top tank can blow suddenly, the $430 for a replacement might be cheap insurance if yours is still original.
Good luck out there.

Ive only been up and fruuning for a few months now, right about the axle add. I am interstate, so every little thing affe ts my and my money when I cross state lines. Thanks for all your help guys, I appreciate you taking the time with your advice and suggestions.
The better organized you are, the better the new entry audit will go and better your CSA score is.

The simplest would be to have a 9000 lb front axle and springs installed.
Can't tell if you have 225/70x19.5's or 245/70x19.5's but 245's have a higher load rating.
Last but some what important is your 23,900 lb rating is already pushing the upper limit of the Allison AT545 transmission.
Nice looking truck, I wish I had your flip forward dog hood, my 93 F-800 has a standard hinged hood, with a 8.3 Cummins it can be a pain to work on.

Lets say you stumble upon the deal of the decade,.... a very nice set of of axles from a heavier F700 or even a F800. You may find that your stock springs will Not work with them.
OR they come with springs and they will not bolt to the your factory spring hangers.
OR they have spring and hangers but they now require a taller Frame.
