I work at an RV dealership and we do suggest sway control products. A rule of thumb, 26' or less, no slideout, use a friction sway control. Over 26' and with a slideout, use a Dual Cam sway control setup.
And how do you address the lack of need for sway control on every other type of ball hitch trailer on the road? If you worked at a cargo trailer dealership would you be recommending the added cost of an anti-sway device? Admit it, the dealership hawks sway devices, the more expensive the better, because they are high profit items. The customers do not know any better, for the most part due to the sway control myth that pervades the RV community.
Transporters (most) are more experienced towing and know how to anticipate what and where things can happen.
The turnover in the transporter business is very high, so "most" of them are very inexperienced. The first TT I ever pulled was the first trailer assigned to me by my dispatcher.
