The damp check was undertaken as soon as we were unhitched, Simon and a colleague entered the van and proceeded to climb over/move our personal belongings in their quest to find damp. They discovered an area under the fixed bed that Simon insisted was really bad damp (£1700 worth of workshop repairs). I argued that this was not damp and was in fact caused by my washing of the van and the water came through the seal on the under bed locker. Simon insisted that a large area of the floor required replacement and as such he was devaluing my trade in by £1000 . I reluctantly agreed to proceed with the deal and regret this decision .
