Just did Adelaide to Perth.
KJ full of crap (weighed at 100kg under GVM with my fat arse in it
)
Roof bars and awning on the roof, no basket/rack tho.
Sat on a GPS 110kph the whole way unless speed signs said not to.
Final economy was 7.9l/100kms door to door after checking fuel receipts.
Here's something I didn't know tho.....
When using cruise control, if the speed creeps over where you set it when you heading down hill, the auto will change down a gear/out of OD to bring the speed back down.
the bejebus out of me when it did it the first time, thought something was wrong with the little blue bus.
