NO CONFIDENCE IN A NEW VAN

Too many stories about damp / water ingress on caravans under two years are putting me off spending on a new caravan.  The letters page (p56) March edition of the Caravan Club magazine 'Complacent?' only serves to make me worry more.  If indeed current manufacturers are showing complacency with the standard of their products, why can we not name an shame them all?  In wishing to spend near on 20k for a new caravan, I'm holding off because the issue of unwanted leakage is offputting to say the least. 
Can ANYONE recommend a caravan that does NOT have water ingress problems?
