On another note, I have just raised my GVM to 5500kg, and with a GCM of 10 000kg.
This is really taking the F250 to the limit, but I wanted this to have the biggest safety margin when towing.
My rear axle rating is now 3272kg, my front is still original at 2381kg.

My F250 is now a Light Truck and hence has a higher rego, and annual safety check. But I now have what I want, and I can tow anything or carry anything on the tray.
My Tare weight is 3850kg (truck, driver, full fuel 400L, Gooseneck hitch, custom tray).
As I now have a higher rear axle rating, I just had to buy new rims and tyres to suit the higher rating.

Hope this helps.

Sorry for taking so long to reply, I have been away with work.
What state are you in?
I am sure my engineer can help you if you are in QLD, but not sure if you live elsewhere.

I will PM his details to you.
Hope it helps.

I am wanting to increase my GVM from 4219 up to 4495kg as my vehicle is very heavy with the steel tray that is on it.

So my current specs are
GVM 4219
Max rear axle load 2760
GCM 9071

I spoke with an engineer from North Qld who was very knowledgeable on the F250. He said that he should be able to up my GVM to 4491 easily, and maybe to 5000 if I wanted to. Going to 5000 would increase my rego quite significantly.
Also he should be able to increase my max rear axle load from 2760 up to 3098, which is basically the maximum of my rear tyres.
If I increase my GVM to 5000, then the GCM would also get increased.

All I have to do is get new heavier rear springs. My original rear springs have 4 springs with the heavy thick one at the bottom, so 5 in total. The new springs I have bought have 6 plus the thick one at the bottom, so 7 in total. I have to measure the thickness of each spring and send him some photos.

So stay tuned. This process will probably take a few weeks, but I will report back when finished.
I won't mention the engineers name just yet, until everything is passed and I have my mod plate.

Any help would be really appreciated...thanks
