About raibourn

  1. I drive a 2017 Thor Aria 3401, my first class A motorhome. At idle, the dash air blows cold as it should, but as I increase speed the temperature rises. I have had it checked by the dealer who is telling me that the rise is small and within expected parameters and that this is normal in a class A. Can anyone tell me if this is true? If not, any suggested remedies.
