Have just done 1050km round trip last week in my 2015 GU N-Treck which has the Nissan bullbar, winch, tow bar, rubber matts, etc and BFG KO2 tyres running at 40psi. Also had two adults in the car with overnight bags and waeco. The average fuel consumption was 10.9trs/100km. Over Easter towed the 2.7t van from Melbourne northern suburbs to the Grampians (via the pentland hills and Moyston) and returned 17.8ltrs/ 100km. I happy with those numbers Sent from my iPhone using Tapatalk Pro
