Question about WD Hitch

[4x4FF]

Guys, I have a question about weight distributing hitches. FWIW, my question concerns a 26' cargo trailer weighing about 9k loaded but I figure you guys are the experts in this area. I have an F250 but have airbags installed on it because I also haul a 5th wheel. When I hook the cargo trailer up to my ball hitch it droops the back end of the truck a little bit but nothing really bad because of the air bags. Is it really necessary to use the load bars or not(I'm not talking the anti sway bar...I mean the weight distributing bars)?

I figure it probably is best to use them but just wasn't sure. What do you all think?

Smoke em if you got em. Thats my opinion. It really all depends on how much tongue weight you have on the trailer, and if the front of the truck comes up more than a couple inches. Also just look at the entire rig from a distance and if you see noticeable dip in the middle, use them.
