When you combine all these factors together , it stands to reason that the longer a caravan is , the more axles it will need .
When it comes to Australianmanufactured caravans , most up to 18ft long are single-axle , 18 to 25ft are dual-axle , and any over 25ft will have three and , in some cases , up to four axles . Of course , there are exceptions to this . If the caravan is designed to be used only on sealed roads , you may see a higher length-per-axle ratio . Also , many caravans manufactured in Europe or the USA may also have more length with fewer axles as the conditions of their road networks are generally better than here in Australia . They also tend to be lighter in construction .
Our dual-axle van was up to the task of traversing The Peninsular Development Road to Cape York .
WHAT ABOUT OFFROAD ABILITY ?
At this point , you may have the impression that the more axles a caravan has , the better . But this is not necessarily the case , especially when you consider towing your caravan in offroad conditions .
Now , before I go much further , it is important to understand that the term ‘ offroad ’ can mean different things to different people . As a rule , we can take it to mean any conditions other than highways and sealed roads . From there , offroad can vary from a straight , well-graded dirt road up to a meandering hilly track requiring a 4WD vehicle to traverse .
