Aussie Traveller bring these in from quality manufacturer Omnistor in Belgium. Electric steps can be a definite safety item as they extend when a door is opened but more importantly RETRACT automatically as soon as you turn on the ignition key. If you are in the "oldtimers forget" category these could save you $300.00 everytime you forget to bring the steps in and we all know how easy that is to do! They are available in twin as well.
