Does anyone have a successful solution to condensation? We are a family of four living in our 6 berth motorhome in the UK. Each morning we have condensation on the windows and damp under the cushions despite closing all blinds, covering cab windows with silver screens and fitting an extra curtain across the cab area. We are tempted to buy a dehumidifier but hesitate at the possible noise it will create. Has anyone found a good solution?
