I drive a Renault Master Minibus for a local Dial-a Ride scheme for a few hours a month.It's a 6 speed manual-rather slow change, with a big steering wheel-feels like a truck compared to my Fiat Ducato Campervan.If you find one with a step by the sliding side door, which swings down and out, look out.Our bus had a worn mechanism and the sliding door fell off on to the road when an escort failed to latch the door right back-the door slid forward and fell off its runners.If you buy a well used example check this out-the doors get a lot of use.The repair cost £1500-the local Volunteer Bureau was not pleased. An electric step which slides out from under the vehicle will not give this problem. The snag is that the door runs along a section of track inside the step when it is closed. When the door is open there is a gap in the track.You may also need to dismantle a ramp or lift from the back.Although the mileage may be low the vehicle is likely to have done a lot of short slow journeys with many stops and starts.
