Finally made the decision to buy an Alphard Camper and picked it up on Wednesday.
A 2010 2400cc, the supplier had fitted a Pioneer head unit and it works fine with all the controls.
Perhaps of interest is the fuel consumption as I have seen a lot of questions regarding that.
I live in Glasgow, got the camper in Norwich. Using the fill to brim and compare mileage with the next fill, it averaged 33.6 MPG on the long trip home
Quite happy with that and it drove extremely well.
