if you're never planning on running or having heat i'd advise you to get a nice 36hp style fan shroud and ditch the heater boxes for some nice "J" tubes. the motor is out and you're right there. plus the parts are cheap and easy enough to install.
also go ahead and get rid of the rest of the heater plumbing underneath the bus as if it's open at all at either end it's just going to be a collect all for dirt, rain, etc.
