Greetings, I have a new to me 2002 Itasca Sundancer 27P. It's a class C on a Ford 450. I can't figure out what the AIR switch is for. Looks like an add on. It sits directly above the AUX batter...
Sch911, you were correct! It is a separate a/c unit for the cabin! It is under the floor in the middle of the forward bay! There are extra vents in the floor near the front of the cabin. Now I know what they are for! I won't need to run the rooftop AC with the generator when we are on the road! Wow, wish I had figured that out a little sooner! Glad to know! Thanks for your help!
