With your WDH. Make it so the front end lift is nullified.
I don't want to start a debate... but.... air bags don't lessen the weight on the RV rear axle nor does it add weight the the front axle, nor does it increase the ability (ratings and limits , etc) of the TV. It only levels the TV by augmenting the rear axle spring's.
If you can't level it with WDH you don't have "enough" WDH.
WDH (IMO), should be properly set up first... Then add air pressure to the bags, if you have them... and if you "need" them.
Typically, air bags are a kind of stop gap. I say all that; but wish my FR brothers and sisters only safe travels of those who choose this route.
Get it weighed, and it you are over, only you can decide what works for you and how far you are willing to push the envelope.
