* Will your trailer have the axle set back at the normal 60/40 (body length in front of axle/behind axle) ratio, will your trailer be loaded heavier in front of the axle, or behind it, will you have it set level to the ground or nose-up (possibly due to tall tires on tow vehicle vs. short tires on the trailer?), and will your trailer have an A-frame tongue or will it be a single-beam? All of these questions will help you determine if you really need help in controlling sway on any trailer, especially such a light weight one.
* I've used sway controls on my tandem axle trailers, but not on my single axle squareback TTT. I do have a weight distribution hitch set-up on the truck, and always use it and a sway control when towing the much heavier (and sometimes not perfectly loaded) tandem trailers (a standard travel trailer, and an open bed car-hauler), but after I adapted the weight distribution to work on my single-beam TTT, it eliminated any sway or erratic travel without having to use a sway control.
* The single-beam tongue doesn't readily accept a WD hitch or sway control because the straight-back placement of the tongue doesn't furnish enough triangulation for a sway control to work properly...the friction surface usually needs several inches of movement, fore-and-aft, to effectively inhibit sway (maybe not so much with a 600 lb trailer, though). I would've had to space the tongue-mounted end of the sway control out a few inches to the side to make it work on my much heavier 2200 lb 4x8 trailer, to get the desired effect. As my trailer is now, after finally leveling the ride height (from 5 inches too high at the hitch, previously), I don't even need to use the adapted WD hitch spring-bar, unless I need to (but I will, anyhow, because it eliminates any problems with bad roads and windy travel situations, and makes the 4x8 trailer travel as if it wasn't there, behind my 12000 lb tow capacity truck).
* If you are still considering using a sway control anyway, then you might need a kit, and a ball adapter (if not using a Weight Distribution hitch shank).
