You will hear horror stories of all caravans. The best advice is buy what suits you. If you are unsure have an inspection report done by a mobile NCC caravan engineer for peace of mind.
Hi, I'm certainly no caravan expert but we've just bought an advante 475 (2001) and we love it. Had a service when we got it and no problems at all with it other than needed new tyres. No cracked shower tray!!
