After speaking with my friend's son, this is his idea of his Dream Home. It has to be on wheels, with a sofa with cushions and a wooden door. A round window would be ideal. I added the curtains for privacy, something he didn't think was that necessary. I also added the table because eating on one's lap is a bit messy plus he might want to work on something or other. He isn't that bothered about that. There's also a big screen TV that is visible from any point in the caravan: even the shower. When he's old enough to drive he can attach a car to the Dream Home and take it anywhere he wants to live. So long as he has a permit and registration. He said "that's fine with me". I told him that the Dream Home can't be any more than about 750kgs because towing it could be a problem. He suggested we take the cushions and curtains out.
