Ducting to "dump" compartment
On our '89 GV the fridge has a compartment directly below it and below that is our compartment with the dump valves.
Neither of our waste water holding tanks are insulated, but I imagine something could be done in that area.
But, what, if any, benefit would there be if a 3" diameter hole is put up thru the dump compartment ceiling into the warm compartment below the fridge? And put 1/4" hardware screen over the hole to keep out critters.
Seems like it would be a tremendous upgrade for our older coaches. I know, an electric heater or light bulb when plugged in to 120V or generator running. But what about when driving down the road or boondocking and having the front furnace on?
The rear furnace doesn't feed the driver's side of the coach thru ducting.
