I was thinking of just this the other day. thinking back to a post a while back trying to come up with alternative heating schemes in AC vans. I think there would be adequate heat in there to make a difference in the van. Especially if the heater boxes were insulated. I was thinking there would be an issue with the water/coolant boiling too easily. So then you need a way to dump the excess heat out when you don't need it in the van. Then you have a radiator to cool your exhaust system? so maybe you empty the system when it is not needed? How about using the fact that it will boil the water to your advantage, like in a steam heat system in a house?
