Hi can anyone offer any advise on the position of the bottom fridge vent I am about to install the fridge an rm212 in my van I have had a look at some pdf manuals on the net but I wont to make sure of the right position for the bottom vent by the looks of it it sits level with the bottom of the fridge is that right Or will that let any wind blow out the burner. plus it says that there needs to be a drop out hole but surly if the bottom vent is level with the bottom of the fridge wont any leek go out the bottom vent
