Renault Trafic Van Camper Conversion

This post is going to be about reliability, obviously. Thats what it says above ^. I find this an interesting issue, especially as its not really been a problem for me, as I've only experienced one break down in my Trafic, and one previously in a friends van. Just before our trip to Cowes on the Isle of Wight last year, around April time, the EGR valve on the Trafic gave up. So the engine just stopped running like I'd switched it off.
