There’s an interesting experiment underway currently which will impact everyone with a RV who is intimidated with the cost of fuel.
One of Australia’s largest motorhome manufacturers, Winnebago, is conducting an RV Fuel Consumption Run from the Gold Coast to Winton Raceway in Victoria to prove that motorhome travel can be almost as economical as driving an average family car.
Led by the NRMA, who also will supervise fuelling of the test RVs, a convoy of four motorhomes of various sizes, a fifth wheeler and a caravan.
At each town along the way, the convoy is inviting the local people to come along and look at the RVs and meet the team including legendary Australian swimming champion, Dawn Fraser, left, a long-time RV fan.
“Rural Australia stands to suffer the consequences of higher fuel costs because if less people travel, less will be spent in those areas,” said Max Mayo, of Winnebago.
“At any given time 75,000 RVs are on extended travel and spend on average $600 per week each on fuel, accommodation, food and entertainment. That’s $45 million per week given to mainly rural centres. It is this that is at risk. [click to continue…]
