We've just returned from a full lap around Oz, towing our 16 49 1 Expanda with our Territory SZ Diesel. Just the two of us and keeping to the speed limit, except in the NT where I couldn't get up to 140kph, we did 34,000kms in 7 months and average 13.1k/100 (from the car's computer). Very pleased with that and the comfort of the Ford.
