n. What heating and air conditioning options are available?

Central HVAC (heating, venting and air conditioning—climate control) systems are available on most vehicles. Some companies suggest rooftop air conditioning and electric heat as opposed to central systems. Rooftop air is a less expensive option, but has a possible disadvantage; the roof top units add about 1 foot of height to the vehicle. This can be an issue in areas with low bridges or with low-hanging tree branches.
