Here are some additional images and information concerning the "Daneste Plus Four" which was a conversion we used to carry out on the Nissan Vanette from 1987 to 1995.

    The conversion gave:  Two single beds or double bed, four forward facing seats for travelling with belts and a four seater lounge when on site - for the size of van (13'1" long x 6'4" high) this was a very spacious and successful layout, even with the beds in place there was enough floor space remaining to use a Porta Potti!
       Most "Plus fours"  had an elevating roof (vertical lift), fridge, two burner hob and grill, cupboards etc.
    The diesel engine (2.0 ltr) would return approximately 35 - 40 M.P.G. and the
petrol (1.5 ltr) approximately 30 M.P.G.
These images are for guidance only, there were a few changes to the "Daneste Plus Four" design however they all had very flat and comfortable beds.
