Fitting roof bed to a 2 berth Symbol/Symphony

After a year of looking we may have possibly found the van for us but unfortunately it is a 2 berth and we have been really holding out for a 4.  Has anyone ever removed the front cupboard on a 2 berth and fitted an aftermarket roof bed?  Does anyone know or think if this is even possible?  And does anyone with a 4 berth want to sell their roof bed?   (Here's hoping!)

With further investigation, I have now found this question has been posted before and it can be done   Apologies!

Well it can be done as you've found out but getting hold of a roof bed for one might be near impossible.

in 2009 when I purchased my Symbol ES there was an option for a roof bed, I doubt whether the factory has any still available but it might be worth a call to Mark in the Service Centre.
