Where are caravans measured from? The measurement SWRV Centre adheres to in describing a caravan’s size is the External Body Length, NOT INCLUDING the A-Frame or Rear Bumper.


What are Electric Brakes? Most modern caravans have an electronic braking system that feeds through the trailer plug. To operate this you need an ELECTRONIC BRAKE CONTROL UNIT fitted to your vehicle. This regulates the amount of power put through to the caravan brakes. An auto-electrician can supply and fit this to your vehicle.


Do I need Stabiliser Bars? Stabiliser Bars or Sway Bars are common names for what is technically called a WEIGHT DISTRIBUTION KIT. Whether you need one or not depends on your individual vehicle and caravan combination. When you connect the van to the back of the car, if they both point downwards, you probably need a WEIGHT DISTRIBUTION KIT. This re-distributes the weight to the front wheels of the tow vehicle, giving a level towing system for safer towing.
