WDH and airbag setup Question

Both the WDH and airbags/stiffer leafs/add-a-leafs/Timbrens/etc will affect the weight on the front axle. The difference is the rear suspension will change this regardless of whether a trailer is attached or not. Ever seen that guy with a whole pallet of shingles in his F-150? The front tires almost come off the ground on every bump. Since he can't use a WDH to transfer the weight to the front axle of his truck full of shingles, the other option, assuming it would not exceed the RAWR or GVWR of his truck, is to have stiffer rear springs. By bringing the back of the truck back up it will restore weight to the front axle and make the truck safe to drive. This can be illustrated with a simple free body diagram.---

Can you post (or describe with words) a simple free body diagram which will show how using air bars to bring the back of the truck up will restore load to the front axle?

Also, can you provide an estimate of how much load is removed from the front axle for a given weight of shingles, and how much load is restored to the front axle by raising the rear with air bags?

Finally, do you have any scales measurements to substantiate this claim?
