I've just bought my first 2nd hand van and was really pleased with my bargain , bought from a lovely old gent who had lovingly cared for it ( or so he said !). Having been dazzled by the pristine interior and barely used facilities I failed to spot the painted over rot behind the curtains round the front window on the inside of my 1994 ABI Marauder 400. I am now worried sick about the structural integrity of the caravan as it appears that any support has gone all down the side and top right corner of the window. My question is simple - how to remedy the problem, how serious is it ( worst case scenario ) and is the van economically viable ie will repair costs outway it's value - I paid 2250. Silly mistake on my part but I'm determined to go caravanning soon - and enjoy it ,depite the bad start
