Rienza Question

As mentioned elsewhere we now are the proud owners of a Rienza. I have had lots of advise about this van from other users, many thanks.
I am now asking the forum in general as this may be common to other vans. On the ceiling in the bathroom, next to the door is a strange fitting. It is oval in shape and swivels under spring pressure.   As it is about six inches away from the wall I cant see it being a hanging thing.
I know it is a bit of a long shot and photos would help. To get photos off my camera via my laptop and windows 8.1 is an ongoing nightmare to be sorted later.
 The Rienza is a big step up from the Duetto and we are eager to try it out. Pity the last owner took the coat hooks and soap dispenser.

  Well I thought it would have a really clever purpose that only Autosleepers could invent . I must dash out and try this clever devise.
The Rienza has some very odd ideas compared to the Duetto we had. The 240 sockets are in strange places. One behind the drivers seat, one behind the passenger seat and one in the TV cupboard. There are no coat hooks any were to hang wet coats.
 I really like the van for its layout and storage but I am doing some sussing and boggling about things to add or alter. I cant wait to get out and try it on site. We have to go back to Norfolk on the 8th of February so we are thinking of staying out for a few nights.
Hopefully one of the better features will be the heater .
