Any Class C *WITH* ducted heated holding tanks?

[Class-C-Guy]

Hi Folks!


Thanks in advance for your kindness and considerations. I've been lurking and shopping the past few months and trying to collect all mfr offerings with ducted heated water tanks. I can always add pads to a ducted area along with additional insulation, but I doubt I can add forced air heat without a lot of modification.


If you own a Class C and know that you have ducted holding compartments, please let me know the model and year so I can target in my searches. Especially ones that have the "winter package" option!


Much appreciated!

Hmmmmm, out of ALL the Winnebago's made through the years, no one can recommend any Winnie motorhome with ducted tanks?

I did see your inquiry when you first posted, and I'm really having trouble understanding what it is you seek. I cannot imagine any condition when you would run heated air via ducting either around or through waste storage tanks. The existing method is to add an insulated heating pad on the bottom of the tank, and only the bottom at that. I am unaware of any conditions where this method is inadequate.
Of course, the fresh water tank is inside the heated coach, so freezing isn't an issue for it.
I do recommend the double-glazed coach glass; great for the cold weather.

Some RVs are designed so that the propane heater floor ducting flows around tanks. They aren’t so much heated, but are protected by the warm air in the ducting.

I don’t know the answer to your question, but I used to be an Arctic Fox TT owner and these are designed that way. I took a factory tour and the sealed bottom of the TT didn’t really have ducting but warmed heater air simply circulated between the bottom and the flooring. The tanks were contained in that space. Even gate valves for dumping were contained in that space.

I have certainly heard of other builders that do this, but I couldn’t tell you which ones.

Everything that I have seen on class C waste water tanks is that they are out in the open under the coach. Ducted air, without extreme modifications would be useless. Adding solid foam or other adhesive insulation would help the heating pad become more efficient at keeping the tanks from freezing. You would also need to insulate the drain pipe or pipes on many of the designs to be safe in really cold weather.

I think you have to buy a Class A unit to get a heated basement. And then not all of them have that feature.

My class A Vista has ducted heat in the water and waste holding tank compartments. I put wireless thermometers in them to monitor the temperature from the cab.

Right on! Thx for all the additional info.


Now if I can just FIND a unit that suits me and get out of apt life!

Don't limit yourself to a class C. Mine works for me but you need to define your needs and find a unit that will fit your new lifestyle, all factors considered. Good luck and best wishes.
