What sway assembly are you referring to? A typical sway bar weighs about 10 pounds, plus the two small balls it attaches to. Perhaps you mean your weight distributing hitch? Can you give us the brand and model of the part you are referring to.
If it is a typical weight distributing hitch, it has a very heavy steel part ~50 lbs that fits into the hitch receiver on your TV. That weight is more than offset for towing when the spring bar is used to transfer trailer tongue weight to the front axle. Hitch components are added to the tongue weight for the purpose of vehicle hitch weight ratings.
If you are concerned about being over weight on the rear axle, your vehicle may have a hitch weight rating specifically for a weight distributing hitch. Or you could go to a scale and get the axle weighed.
I have used a sway bar when towing for "insurance." It makes me feel more comfortable when passing an 18 wheeler. But it is no substitute for a properly balanced trailer. The hitch parts that attach to your TV are not added to the tongue weight when checking balance.
The only drawback I have found is that sway bars can be damaged, or cause damage, if you make a very sharp backing maneuver that jams the bar all the way in. Since our short AFrames can jackknife so easily, it is best to remove the sway bar when backing. At least until you get a significant amount of experience and know the limit of turn the bar will allow.
