Thanks Richard,
Just been talking to my partner who said we might need the pop top to make thing like cooking easier but in the scheme of things, quite expensive in itself.
It only needs to transport four and sleep two. It will predominantly be used for weekends away with the odd week in the summer so it may only need to be a 'day van' depending on what that actually means. The absolute key thing is being able to sleep comfortably so I guess I could research if there are DIY things that could be done to convert the existing seats and see how much the rear conversion kits are which get the hob and sink.
We're also open to alternatives to the Alphard that may be easier to do some of the stuff DIY e.g. a Transit but the Alphard does look appealing!
Thanks
Dan
