While WDH's are widely used by folks here, I get the impression that, in contrast, anti-sway bars are not. The TM axle is further back on the trailer than many travel trailers. That increases the tongue weight, which helps to reduce sway. The distance between the TM axle and the hitch ball may also be a factor, I don't know.

I've towed our TM many 10s of thousands of miles over 12 years of ownership, including 3 trips across the U.S., and despite my not having an anti-sway bar, or similar functionality on my WDH, I have never had a problem with sway.

Others here, like Bill our esteemed moderator, have even more towing miles under their belt.
