Sorry Anthony and Sophie- I don't look on the forum as often as I should and only now spotted this thread. We've got a 545 having ordered it when we saw it in pre- production form last August ( liked the layout so much) and have used it now for two eight night holidays.
Generally we are very happy with it. Plus points being the amount of lounge and table top space. Also like the look and spec on it with the TV storage etc. It's waiting to go back in to dealer for a couple of minor issues.
Any more queries come back to me,
Carwyn
