Hello, im looking to buy a caravan and have a small budget, I have found an amazing avondale osprey 2005, however there is a few issues which need attention. The interior and chasis looks immaculate. There is some pimpling on the walls, however when I used my damp meter it came at 0 and no damp to the touch. The front side of the caravan had mold on the windows at the bottom only small amounts and the damp meter also read only 0-8% The whole caravan was around 10-11%. The bathroom had a small issue at the bottom of the wall which would need addressing. The wall is spongy with no water or damp to the touch, however read at 70%. Would this be a simple job to fix or would it be hard?
