I have a 2002 Lincoln Town Car, which has air suspension instead of coil springs. I need to carry electric motorized scooter for my father. It weighs close to 300 pounds.
My quesitons are: 1. What is the safe maximum weight I can carry on the trailer hitch on the car. According to the hitch manufacturer, 300 pounds is O.K., but I would assume that is when the weight is on the trailer hitch ball not when there is a tray-like thing carrying the scooter. (The scooter would exert more force/weight on the hitch, because it would be extended out from the trailer hitch/ball.)
2. Will the air suspension be able to take that much weight without malfunctioning? I ask this because to maintain the same ride height, the car would try to put greater pressure into the air suspension bags, which will ultimately result in failure or premature wear. Does the system have maximum tolerable pressure, so that the car would begin to sag rather than over-inflate to maintain the ride height and go bust?
I see a lot of people in Lincoln Town Car carrying electric motor scooter for disabled persons, so I am assuming it's O.K., but I just want to make sure. Also, what happens if the air suspension bags go bust? does the car sink?
