Pair of F100's, San Antonio

Erik Baier caught these Ford F100's on the streets of San Antone. I'm guessing the white one's 1969 and the red, a '75. But I'm always wrong with Fords. Like the looks of this Ford generation. Drove one around Banff for a couple summers.
Then there was the orange 1974 F-250 that Jarrod McCabe piloted from Montana to Massachusetts a few years back.
San Antonio does look very green from a New England February point of view. Also compared to Trans-pecos Texas which is sunny and tawny under a blue sky, in February. Except for those mountains (Fort Davis, Chisos) which look purple seen from a distance. Am I homesick for Marfa, or what?
