Heat duct size
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" ...

Yes, that is normal. The reason for the smaller ducts is to limit a large volume of hot air where it is not needed. You sleep with sheets and blankets. You would get too hot if they ran larger ducts. They also do this for the bathrooms also. The more heat(volume) going to the tanks is less heat to the inside of the RV. If they run larger ducts to baths and bedrooms, they usually install a duct grill that you can shut off or lower the volume of air. Doug
