    Just come back from a weekend at flamingo land near Pickering in Yorks.A great weekend for those of you with kids or even if your young at heart! Free unlimited access to park and zoo included in price of pitch (off season only)
    There's also an indoor pool and evening entertainment
    Anyway back to the point,there were 5 of us in the van and by morning there was heavy condensation on the windows and on the roof of the over cab bed where drips had fallen onto duvets.at the risk of sounding a bit dim what causes this and how do you solve the problem,if you can.

    No ventilation causes it, along with people breathing, and ventilation gets rid of it.

    2 roof vents were open albeit not fully.So is the answer to open more and turn heating up.What about on Rainy nights will water not get in.

    It is worth checking all gas drop holes are actually still holes and that door/fridge etc vents are still vents and have not been blocked off inside !! ( as some of ours were )

    The silver screen and webasto diesel heating seem to keep the condensation at bay when were all in the MH . Thats 5 people and 2 dogs. We dont open any windows BTW.

    It happens when warmer humid air is next to a cold surface, can also occur outside too, it's called dew.

    The colder and stiller the night the greater the problem. As others have said, warm moisture laden air coming in contact with a cold surface - such as windscreen glass/cab windows. How insulated is the skin of the overcab? May that be a problem?

    Surely sleeping with heating on won't solve it? The warmer the internal air the greater amount of moisture the air can hold - the greater the condensation. But maybe the fan in the heater helps on the ventilation front.

    Wholly agree ventilation is the answer.

    Got to assume the insulation is sufficient as its a well known manufacturer and the temp was not below zero.There is a blown air system in the van but she who should be obeyed objects to the noise.Come to think about its her who moans about being cold,did someone say if I could stop her breathing that would solve the problem ?:Eeek:

    Each person breathes out about 2 pints of water per night, ventilation/heat is the answer.The water hits the cold spots ie windows, either vent or turn heating up::bigsmile:or stop breathing

    Hi . If you have water dripping of the ceiling over the beds, I sujest that the insulation value in the roof is inadiquate, especialy if you had the roof vents open a little.
