KK for us we have 6 and 3 year old girls. On quick trips they can sleep on the hard floor and for longer trips there are the various kids room options. The kitchen and access to on the move is awsome on the KK's, I dont like the way the kitchen swings back close against the canvas on the Aussie swag and others similar.
I find it hard to believe that the TVan would be easyer to set up than a KK for quich overnight stops, 6 latches, flip it over and you are in bed.
Its a lot of money to spend on eaither so I would hire a couple first to make sure you make the best decision.
