Most of the DC-10s in service in the US are used for fire fighting.

Yes, but there are many MD-11's still flying as freighters. There are four fire-fighting DC10's out of ~8 still flying, but there are 25 Mad Dogs (MD-11) at UPS, 38 with FedEx, and Western Global has 4, so there are plenty of MD-11F's around.
