So far very happy with my 2010 GU tray back that I got 2nd hand with 18000 km on it last year. Only one minor issue I've had was a small crack in the dump pipe that turned out to be a dodgey bit of welding - replaced under warranty with no questions asked even though servicing has been done elsewhere. Fuel economy varies depending on weight towed and my right foot but empty and normal it's 12-13 lt/100 but punted hard and loaded plus towing it can be a lot more.

Cheers Nip
