I apologize for giving input that was contrary to your views and will try to refrain in the future. That being said, I would like your thoughts on this; When you have a real heavy load in your bed, the front of your truck is lifted up two to three inches and have a lite steering feel, what is happening and why the light steering. Thank you
I understand that you are dropping the rear. It depends on where the weight is placed.
500 lbs at the rear most point of the bed will take weight off the front axle.
500lbs over the axle "shouldn't" take weight off the front axle, and maybe not even add weight.
500lbs to the front most point will add the most weight to the front.
But air bags are right above the axle. They push the frame up, and push the rear axle down. They don't transfer weight, but they just take weight off the springs, not off axles. They don't add any weight to the rear axle, they just place it differently. Yes, lifting the rear may shift the center of gravity, therefore shifting weight from axle to axle, but I don't see how it will transfer much.
Like I said, I'd love to see weigh tickets of before/after bags because I wanna know for sure.

When I get back from our travels I'll see if I can find a weigh station that will let me do a double weigh in and post what I find.

Nothing personal, but you thinking is way off . You have not added, changed or transfered any weight with addition of the air bags. All they do is prop up the rear end.

A 5th wheel has the pin and thus the weight over or slightly forward of the rear axle. Very little weight is added to the front wheels. Now on a bumper pull without a weight distributing hitch, dropping several hundred pounds on the bumper, you will unload the front tires. The WD hitch will transfer part of the weight to the front tires and some to the trailer axles.

If you raise the rear of the truck with air bags, all you do is prop up the back znd transfer no weight.

I could be way off, but don't think so. When you place 2500lbs into the bed of your truck and it raises your front end up 3+ inches and your steering is light. As you stated, you are unloading the front tires Where is the unloaded front tires weight going?

But proping up the rear end does not transfer ay weight to the front. All the weight is still in the same place.
