Question:
Hello, I have a 2022 Toyota Highlander AWD with factory installed tow hitch. Im towing a 2480-3500 Casita travel trailer with an Anderson weight distribution hitch. There is some sag on the rear end of the Highlander. What can I do to reduce the sag? Someone suggested air springs, but I dont know anything about them.

Hello again Mary; air bags like the # F2430 you were looking at aren't available for the 2022 Highlander. What you can use instead is the Coil SumoSprings Custom Helper Springs for Coil Spring Suspension # CSS-1145R. These fit in the coils of your springs to add additional support to help reduce the sag you're experiencing.
Realistically a properly setup weight distribution hitch should keep you from sagging. However, the Andersen is pretty bad (I know, I have one) so I'm not surprised you need additional support.
