Hi Gray and thanks for the reply, I popped out again today as its been a couple of weeks since I packed everything away and put the cover on. Nothing has changer the inside is exactly as it was before with just this little bit of delaminating, I cant see any signs of damp any where, how ever I will invest in a meter and check it out properly. It is due a service so I could ask them to check it too. Having seen that its still the same today Im not to concerned about it, I was expecting to see mold every where. I have left some de humidifier packs in there, the sort with granules and a catch tank, we have used them before and if there is any moisture in there they will show it.
The first thing is to get a Damp meter and check if there is damp that needs curing before you go start repairing Meters come in all prices obviously the more expensive the more sensitive but spend what you can afford over £15 and you should get one that gives you a decent reading either by sound or visual indication if it is damp then you need to find where it's from so you can fix that first then after the leak is solved Heat and a decent powered dehumidifier before fixing anything else Can tell I've been here myself two caravans ago AND a couple of months ago when a hose decided to part company at a junction and flood the caravan and although we emptied the physical water out within 5 minutes the residual damp took 6 weeks (yes SIX weeks) to clear up
