I have a front bedroom TT. The duct work that goes to the bedroom is small - maybe 1" it doesn't flow any air to speak of. It's the same size as the duct that terminates under the TT for the "heated" ...
I spoke to the dealer. The official factory test to determine if there's an air flow problem is to put the fan on and see if a tissue moves. So it's all good as far as the factory is concerned.
We'll see how the winter goes. The suggestion for using small electric heaters is a good one that should work well.
