Slicko

I am planning on spending some time in outback and in the Gulf Country of North Queensland. I will be towing a Jayco camper trailer and with the Rav's 60 litre fuel tank I have concerns relating to some of the distances that I expect between fuel stops. The vehicle was bought new in Dec 2011 and all I can get at the moment is a rough fuel usage around the city. I have made enquiries regarding long range tanks or auxilliary tanks with no success. I am not keen on carrying jerry cans inside the vehicle and I don't have any knowledge of any restrictions on installing some on the drawbar of the van. Is anyone able to help with any advice?

G'day! I'm looking forward to catching up with other Toyota owners especially those who have Rav4 AWD. I've had a lite ace, a vienta, I've stilll got a camry and I've just bought a 6 cyl Rav 4 AWD. The "treasurer" and I are planning to tow a Jayco Eagle around Qld in the next few months and we are sure looking forward to it. Hopefully we will get to meet other like minded Rav4 owners Hope to chat with other Rav4 owners who have terrorised the back blocks or are in the process of doing so Slicko
