One of the great things about this forum and meets such as the Dorset one, is that you get to learn stuff about your Cali and what may be missing. In our case, we learnt from Jane & David (who'd only had a Cali for 2 days) that Ocean Edition models are identical / from stock and are all supposed to have the bed comfort / bed extension package (or whatever it's called), whereas we'd been sleeping on a bit of foam about 2" thick with nothing in between our bottom halves and the bench. It wasn't too bad tbh!
There were other 3 Ocean Editions at the meet and they all had the better mattress, so I went armed with this info to the dealer this morning and they agreed it must have been swapped out to another Cali, so they swapped ours with another Cali for the thicker one that folds out over the bench seat. Result and without the meet we would have been in the dark. With specicial thanks to the other Ocean Edition owners
@motacyclist and
@GillianC (I think) and Jane & David (don't know your username sorry).
PS Don't buy the 2-tone Cali ocean that's at Sinclair in Cardiff as it will have our old mattress that's been used for the last month and a half
