dura therm comfort control thermostat

Is there anyone around the Waco or Dallas areas that could help me with this RV? I did everything you said Doug & got it working fairly well but it still goes from zone 1 (front air only) to zone 3 (both a/c units). I can't get it to go to zone 2 which I guess would be (rear air only).
I'm also needin someone to take a look at this generator & someone to just check out the gas (lp gas worries me) toake sure no leaks & everything works. & the electrical. the lights on my slide out do not work. thanks aging for all the help
