Steve,
Here's the short answer: If your receiver is rated for the tongue weight, it's no problem to just use air bags. If not, you need the WD system so that you're within ratings.
The real thing to look at is the ratings on your receiver. That 9K trailer probably has 1,000lbs tongue weight or more. Is your receiver rated for that much WC (weight carrying) capacity? If not, you'll need to use the WD bars so that you're within the limits of the receiver.
My old truck was a chevy 2500HD and I installed an aftermarket receiver with 1500lbs WC, 15,000lbs WD rating. My TT has about 800lbs tongue weight. Technically, I could pull the TT without weight distribution and be well within the limits of the receiver and the truck. I did that a few times and found more bounce and spring action than I preferred. When I used my WD system (nearly always) the connection between truck and trailer felt much more secure and made bumps and bridges much easier.
