i like the heater in that big old van, I personally think this is one of the best multi functional hot rods I have seen, we like to go camping so a nice econoline is a prospective project for me , you could easily cam a bunch of camping supplies in the back. plus firewood, and have room in the truck to sleep if the weather gets really bad, you could put an rv hvac on the roof and have a party in the back just pull up and plug it in ... hmmm
