The wagoneer s3 with air suspension towed great. The air ride and ability to raise and lower the vehicle made towing smooth. The trailer is a 10400gvw car hauler. The defender is a 2022 max limited. We averaged 14.5 without the defender. It’s hard to tell on the way back what average was. We hit so much stop and go train it wasn’t a fair run. The longest part we got clear was about 45-60 miles and the car said 12.2 with us running 75-82.
