I know that the RAWR is the weakest link in this set up. An F250 has a Visteon rear axle MAX rated at 6200# and the F350 has a Visteon axle MAX rated at 7280#. So realistically no amount of suspension mods are going to actually increase the amount of payload this truck can carry due to the lower rated axle on the F250.
Ford fleet service specs shows its the exact same Visteon rear axle/brakes on the F250 and F350 SRW trucks. The F350 SRW has a higher rated rear spring pack that gives it a higher rating.
GM and Dodge/Ram use the same AAM 11.5" rear axle but give it a 6200/7000/7050/9850 RAWR with different spring packs/higher rated wheels and tires.
Visteon says the axle has a 9xxx lb rating . Ford as GM and Ram simply uses different rated rear spring packs/higher rated wheels and tires to get the rating they want.
This is how owners safely increase payload ability.
I see the V10 has up to 26000 GVWR in motor homes and tow rating up to 18000 lbs in the F450/550 trucks. Your V10 won't have any issue towing a 13k-14k trailer.
The biggest driving factor in the lower rear axle rating is TIRES! Then the spring pack. stock tires on my Ram had a weight rating per tire of 3,042#, GRAWR of 6,084#! my Ram with Camper package came with tires rated at 3,415# ea. and one ton spring pack, still 8,800 GVWR!
Just looked at putting 17" wheels on the truck to put a larger rotor on the front, the 17" tires LOST 220# of capacity per tire (3,195#), I will stick with the 16" wheels and premium brake pads and parts.
Don't forget as the weight rating of the V10 goes up the differential ratio goes down (higher numerically)some into the 5.xx area.
