My Truma auto changover/sucure motion regulator has packed it in, and in view of the extortionate price of the Truma I have found on the gas-it site a Cavagner 30mb micro changeover reg. for £31-00 This looks ok to me but comes as 8mm or 10mm outlet does anyone know which one I need for my 2007 Rapido and also it is suitable please?
