Reviving this post as I have been dealing with some mould issues with out CT. The statement "fold it up dry" is hard when the humidity level is somewhere about 60%. What is dry enough is the question. Anyway, after the wettest year In Ingham since 1970 and our first year, and after 8 or 9 outings during the supposed dry season, I had not had any issues. If I had packed up wet, I would errect in the back yard and leave until we got atleast 3 or more hours of good hot afternoon sun. Of course the bottom of the tent is still wet, and its a pack up a bit, dry and bit more job. But so far no mould on the main tent. But, the drifta kitchen is horrible for mould. I have often pulled it out and left it in the sun for a while to try and keep it at bay. I recoated the wet area around the sink with marine varnish, and that has helped, but its an ongoing issue. Today it was hot and sunny, so put the tent up, pulled the kitchen out and washed the kitchen down with a light bleach solution and left in the sun to dry for 4 hours. It was hot, 35c and a gently breaze. I then pulled the drifta storage box out to find mould all around the end boards, and on the canvas bag that holds annex. The sweet smell was ripe, white blotchy mould had begun to develope inside and out of the bag. The annex walls and roof dont appear to have mould on them, although there was a couple of spots where there had been contact with the bag. I wonder if the bag is more susceptable than the tent as it has some air ventilation in the trailer which might aid moulds growth? Again I washed down with a sponge and light bleach solution and they are out in the sun drying, as is the drifta storage box. I will keep an eye on it, and might leave the annex out of the box for a while and air out as much as possible for a week or two. I am not that surprised that something is going mouldy with the wet we have had. but the mould on the ply and on the storage canvas bag has caught me by surprise.
