I’ve just come back from a month long drive from Wodonga to the Flinders Ranges. Towing the van, I normally drive at 90+/-5 kph. Fast enough not to be a road block, but slow enough to be easy to pass. This trip though, the roads were in such horrendous shape that even 90 was mostly wishful thinking. Over the entire 5,000k we only saw a couple of suicidal drivers…those for whom double lines are an invitation to overtake. As usual, the road train drivers were professional and easy to deal with. Coming back via Geelong and Melbourne was the hardest part of the trip, as the ring road seems to bring out the maniac in so many.
Lost the windscreen on the first day, to a truck that was throwing stones from its uncovered load. RRS windscreens are expensive, and proving a bit elusive at the moment. Fuel consumption for the entire trip, with about 4k of the 5k towing, came in a 10.1 lt/100km. Proof that drag relates to Vsquared, I guess.
