Towing a 3500lb trailer (380lb tongue weight) with a 2021 4Runner. Horse power wasn't an issue, but the weight of the trailer was pushing the 4Runner around, especially over 55 MPH. Getting sway on the highways as well as a generally exhausting herky jerky ride. Steering was sloppy because of sag in rear suspension.
Installed the Andersen Weight Distribution No Sway hitch to remedy the problem. It really does work. Much easier to control now. Pleasant to tow and worth the money.
