Hi There, I am having rain leaks in my camper and after much searching, we think it could be coming in via the vent from the gas fridge. Does anyone know of a vent which is adjustable and possible to use with a gas appliance (as many say not) or or some kind of a cowl to stop the rain coming in, it has nothing at the moment and we think this could be the culprit. I appreciate it would be dangerous to shut the vent when the fridge is operating but there are many times when it is not and it would be really useful to be able to shut the vent or as I say install one with a cowl if such exists - thank you Sarah
