Got it was not aware of the new roof airs. In return not all country coaches front rear zones r controlled by the roof air thermostats. There r others that have separate thermostats for front and rear interior zones on the older conversions. There r others that also include a webasto programable remote u set the time on and can run on timed sequence when leaving for a weekend or something or to preheat prior to start up ect on some newer conversions. I just did work on a Vogue and they chose to eliminate everything accept going into furnace mode in zone 1 and 4. PERIOD Nice. A furnace that turns on with 1 switch. Imagine that. Good job Mr Vogue but it would be nice to have it more up on the dash its up your left armpit where it is now.
