looked at a new grayhawk 29mv today, we want to go from a tt to a class c,wife likes this one, some things i noticed that seemed strange to me,#1 no ceiling exhaust fan in the kitchen just the stove vent,#2 large exhaust fan in bedroom witch in my tt the large exhaust fan is in the kitchen and a small one in bedroom and bath.is the large fan in the bedroom because it is close to the shower?
