"Calista" Trim 1995 F250? I bought a 95 F250 from my grandfather.

It's an original 1995 with 460 E4OD with only 80,000 miles on it.

It has the words "Calista" stickered on the bottom of each door. Under the mirrors.

My grandpa doesn't remember what it was, but swears it came that way from the factory. 

The truck was built in Canada and shipped here. He bought it with 0 miles. 

Anybody know anything about what it means?

It's nothing special, firetruck red, chrome trim on everything, red interior, cloth bench seat with lumbar adjustment and adjustable headrest, electric windows.
