I also remember when my dad had a WB van and a HZ tonner at our pet shop. The van heater had to work a lot harder as the heat went stright up and into the back. |

You could try having the LPG converter plumbed to the return side of the heater so the heater has first dibs on the hot stuff, then off the the converter???
