I have it in my head I want to install an Red Dot brand cabin heater in our 1986 E32-3 that uses engine coolant for the heat source. We motor a lot here in the Pacific NW and capturing some of that waste heat just seems like a good idea in these cold winter months. I have kind of looked at where the heater might be installed and how I might route the two heater hoses and see no real obvious perfect setup. Perhaps some of you could offer some suggestions on locating the heater and where to route the hoses (or air ducts?). I have bought nothing yet, but the local boat show is coming and ..... Thanks
