[FC] Heater Coil

[DIODATO]

Has anyone tried, or would it be possible, To make a hot water heater for a
Rampside. Make a small diameter coil inside the engine compartment and have
it run to a "radiator" in the cab? I saw a small Radiator/fan unit in the
recent JC WHITNEY catalog. This would eliminate any potential CO or smell
issue.  ..... Or do I really have to take apart all those metal and 'glass
boxes to replace the rotting insulation :o(
THANKS
