I found a few example in a van enthusiasts web site where the members did just that. Using common house furniture and very little carpentry/metal works, they managed to create very impressive results with a down to earth budget.
|Using a camping bed and some small shelves, this van owner transform his standard van into a homely camper|
|Another example of minimal carpentry works with impressive result|
|Another view of the same van above|
|Using a standard Ikea sofa bed, and shelves this van provide a comfortable seating for day configuration and a full size double bed for night!|
Below is a more elaborate conversion example, it is still a simple conversion with no structural or seating changes. The end result is a very versatile camper where all the camping components can be removed to free up space for daily use. When it is time of road trip, the washing sink and stove cabinet be easily installed. What impressed me is the use of platform system to create a flat sleeping surface.

|With the seats folded flat, the platform can deployed to create a flat and comfortable sleeping surface|

|The stove cabinet is a self contained unit, with a portable stove, clean water tank and waste water tank to complete the closed circuit plumbing|
The camper conversion example below adopts a modules concept. The stove, the washing sink, other storage compartments are made of identical size modular boxes. This may not be a fully fledged camper but it will useful for day trips and picnic outing.
|The collapsible water is usually stored in one of the modular box, so is the sink|
|Like the sink, the stove is a simple camping stove with aluminium heat shield propped up for use. When on the move, they are stored in their modular box.|
|Storage for other stuff|
|The bed don't look like it can support an adult, probably for small children only. I believe this concept is borrowed from VW Westfalia's child bunk design, which also make use of the space at the driver's cab|
|A small television for entertainment, but I think a sun shade DVD player is probably a better alternative|
|When on the move, everything is neatly stowed away|
