If anyone has a hymer CL 554, does the lounge bed change into a double or a single? We like the look of the layout but trying to see the difference between the SL and the CL. I know the SL has a double floor but what are the other differences. The CL has the option of a drop down electric bed which we don't want prefer a made up lounge double. The data seems to imply single but the lounge is the same size as the SL. Really puzzled and can't see one in the flesh to look at.
