Sorry, Biscu2ski, I dont follow, info missing. You keep mentioning sag like it is magic and going to throw weight all over and make it go away. I dont know how this is relevant, do you?
The point of bags is to keep vehicle level, so talking about how sag will minutely alter weights slightly is not relevant. Bagged trucks ride level! WDH trucks generally ride level, so we are talking about level.
Put in your formula a 900 lbs motor way at the front of a long truck and see how much hitch weight it takes to lift that motor alone, not to mention other components. I think you will see quick we are talking NOT about front end weight, but, rather, hitch weight and weight limits of the components of the tow vehicle, which is usually wheels/tires.
The only number that seems to matter is what the truck can carry (payload) at the rear.
WDH, and air bags might level the TV, but I don't think they act the same. Tongue on ball, force rear down, the front comes up. A WDH will level the TV by forcing the front back down.
OTOH, air bags will level by lifting the rear.
With no other changes, lower ride height will handle better.
