My M/H is built on a new Peugeot Boxer I have had a look behind the cab courtesy lights and there is a spare cable with connector unused. An OE option for these cabs is a Monitor that repaces the rear view mirror for reversing and a few other funtions. Has anyone fitted the OE monitor and if so what camera did you fit and more important what is the cost. Will this be better than an aftermarket monitor and rear camera ??
