That sounds like an interesting setup but I doubt it approaches 29MPG. Fuel costs for getting to the track was the major reason I wanted a van. This thing is built on the Focus platform. They basically took the front half of a Focus and welded it to box. You COULD sleep in it too but you’d have to remove the karts and I would have to have A/C in there at night! Anyway the setup you mentioned sounds cool. I’d like to see some pictures of it.
