We have a 2002 Coleman Mesa popup which weighs over 2000 pounds and has a single axle. We tow it with a 2015 Tacoma Prerunner w/ towing package. We occasionally experience some sway and "wagging" at speeds above 50mph. I was considering adding an Anti-Sway Bar to our hitch (NOT weight distribution, only anti-sway) like the CURT 17200 Trailer Anti-Sway Bar Control Kit (https://smile.amazon.com/dp/B000HLO7QA/) just so we have some solid side-to-side damping when the swaying wants to start. We do load 60% front / 40% back as much as possible. I am wondering if this would be overkill. I am also a little hesitant to drill the 4 holes in the trailer tongue that the installation would require (see picture). Any thoughts are appreciated.
