hi there
i havent done any static caravans, but my concern would be the amount of laminated products in the structure and fittings, the heat control is critical to ensure that the laminates dont start to debond.
weve dried out places in freezing temperatures, one thing that we have done many years ago, was to heat a house up for short time to get rid of the worst of the moisture, before starting a controlled dry.
i think that the heat drying is fantastic, but there still seams to be an element of resistance amongst the authorising authorities in the UK, when its used so widely in mainland europe and usa.
have a great weekend, and keep warm
regards
martin
