We have a Compass Rallye 634, 2007 model, purchased as new in May that year and we use it frequently. It has an L-shaped lounge and after a few months the floor in the kitchen area, seemed to be worryingly springy. A response to a letter in Practival Caravan suggested that this was nothing to worry about as modern caravans are designed by computers - maybe that now has me MORE worried! Has anyone else experienced similar springy floor problems? One caravan engineer has suggested pumping resin between the floor layers. We'd be grateful to hear other folks' experiences and solutions. Many thanks, Sue.
