Had a manual 2013 2.5TD. Used to tow our Penguin -1500kg loaded, and was more than adequate and reliable.
Tried towing our AT11 several times, at 2200kg loaded had a really hard time trying to keep it all together. Weight of trailer just bullied the poor Triton. Struggled uphill with AT11. I wouldn't try taking on Fraser but others may. Have towed a 650kg Cameron soft floor on Fraser, wouldn't like to try something 3 times that weight
Around 12.5lt/100 with Penguin, 15lt/100 with the AT11. 8.3lt/100 not towing (city and Illawarra ) fitted with a RaceChip that had very slight improvement on economy and moved torque curve about 300rpm lower - measured by seat of the pants
IanC on here also sold his Triton after purchasing a Reconn(lighter than AT11) maybe send him a PM too
