The purpose of the weight distribution hitch is to compensate for the fact that you are putting several hundred pounds of tongue load some distance behind
the rear axle, which means that its effect is to increase
the load on the rear (driving) axle and decrease
the load on the front (steering) axle. From the safety standpoint, the reduction of the weight on the front wheels--and consequent reduction in steering ability--is the more important of the two effects.
I am not familiar with either the Sequoia or the Airsafe hitch, but my tow vehicle has two tongue weight ratings, one for a deadweight hitch and one for a weight distributing hitch. The limit for the deadweight hitch is only a few hundred pounds; anything over that and you need a weight distributing hitch. The air suspension can adjust the front and rear ride heights but it does nothing to change the weight distribution on the front and rear axles.
Sway behavior--the tendency of the trailer to steer the tow vehicle, like the "tail wagging the dog", depends on the relative weights and wheel bases of the trailer and tow vehicle and the distance between the hitch ball and the rear axle. The longer that latter distance the more sway you are going to have.
We tow a 4,000 pound gross weight 1980 International Caravelle 22 ft trailer with a 7,000 pound gross weight Silverado extended-cab short bed pickup truck. Depending on the tank status the tongue weight is in the 4-500 pound range. We use a weight distributing hitch with only light tension on the bars. We no longer use the friction sway damper that came with the rig and I have never been able to detect any sway with or without it.
Look at the weight ratings of your hitch receiver and tow vehicle and decide for yourself. My best guess is that you probably should have some weight distribution.
