Just for fun..As most of you will know from previous threads our van has a small water ingress leak where cab meets hab. To avoid it getting any wors, e several weeks ago I turned the van around on the drive to stop any more ingress. Theres been no heating on inside. Last week mum bought a domestic compressor dehumidifier, today I've put it in the van, any guesses as to how much water it will pull out in a 24 hr period?
