And we need to make sure people don't get hung up on the word "knee knocker"..
This doesn't mean that it knocks your knees when you get in because my 6 foot 4 friend has plenty of legroom with it hanging in the passenger side. I believe it refers to if you were to hit the brakes and get it in an accident or something...
Most vintage air and old air systems are in the 13 to 14,000 BTUs.. when you feel that 22,000 plus BTU you'll know your money was spent well...
