Hi guys, just looking for some advise. I own a 2003 3l td GU it's pretty much stock we have just returned from a trip across The Simpson Desert and the truck preformed great. But we are now thinking about getting a caravan or camper trailer. I was wanting to hear people's thoughts on towing, should I get a chip and exhaust fitted for a bit more grunt or should I consider something bigger. Would I be putting to much on the 3L towing something? Thanks in advance guys.
