We always use the Blue Ox 1000 with sway - previously an Equalizer. Our trailers and tow vehicle need that stability. As noted, you have a lot of experience towing big, small and in between, but driving an 18 wheeler is a lot different than a travel trailer behind your truck. Winds, gusts from the large rigs, unexpected crisis situations....the WDH and sway could save your hide. Nothing is a 100% guarantee, but in the interest of safety for you, your family and the rest of the road, it's pretty cheap insurance. The smaller the trailer does not necessarily mean there is less need for WDH/sway....they're lighter and more susceptible to winds. For a few minutes to hook up, around $500 in cost for a quality one and the peace of mind, suggest you add that.
