I have a Elddis avante 540 2010. Used this weekend 11/11/11 to 13/11/11 and a friend was towing their caravan behind us and noticed that our caravan was bouncing alot. At one point it left the road and skided, which we noticed as well. Is this a big problem.
It could be that you have a flat spot on one of your caravan tyres. This will need to be looked at straight away. I would suggest that you ask your local caravan dealer to look at your caravan.
