Hi Rodders.
I'm new to owning a Commer but one of the things that made me prefer them over the VW's was the extra width that allows you to sleep across the van, which leaves the rest of the back of the van free. I know they're not all like that, but it just appeals to me, and being a short arse, i can sleep that way easily.
I suppose it comes down to personal preference and what works best for you.
