OK sounds good so far but how low can you go? I mean what is the travel of the level low system? How many inches does the bus go up & down? The specs @ the Thompson site that Jon just brought up indicate their height to be about 13 ft. so with Gary @12' 7",Ray @ 12' 2", and Tom @ 12' 6" do you think a 12' door is tall enough?

What is higher above the roof, the satelite dome or an airconditioner?
