condensation on the inside of THE CARAVAN

Hi Tom,
the new van is an Atlantic Murchison 24ft long,meranti framed with ali cladding on the outer skin, fibre insulation, and built for dirt road travel so she is big and at 2.6 tonne reasonably heavy.
with the top hatches partialy open it should not get this amount of condensation in it of a night time.

Spot on Notso,

The first night of our June honeymoon was in a camper trailer at Corryong in the Snowy Mountains. Our exhaled breath condensed on the canvas roof and then rained on us! Next night I set up a blanket as a ceiling...... stopped the rain but the condensed moisture then froze solid on the canvas roof.

Back home I fitted a yacht ventilator at the apex of the roof and never again had trouble even though some heavy breathing continued through the continued ownership of the camper. lol

Good morning all,
I had a very interesting visit to one of the caravan yards yesterday, and it would appear that they have left out one of the ventilation scuppers on our van so we are having another one fitted I also learnt about the top hatches that we have on our van and how they operate so hopefully this will solve our problem.
thank you all for your input and heavy breathing facts and condensation.

Good morning Ozi M,
the old van was a roadstar Voyager, it was built in 1995, and she was big at 21ft shower and toilet east west bed, and she was comfortable, and she was our first caravan, to say we were and still are in love with it is an understatement. It has now moved on and the new one is built to what we require, we hope.
The build on the new van is good , but the finishing touches leave a little bit to be desired, this van is built to do dirt road travel, and the insulation is exactly the same as the old van.
we were cooking inside and had the oven going for the roast dinner, that certainly warmed the van up, so much that we never turned the generator on for the reverse cycle aircon for heating, and the van stayed warm until we went to bed, it wasn't until the next morning that we discovered the condensation and when that happened two days in a row that is when I decided to ask the questions. WHY.???
To be honest I never thought to run the aircon on fan mode only, or dry, thank you very much for the information. We shall try it next time
