I agree Tony, while I love the no side trim look on my Fleetwood, I just can't take a chance parking next to someone in a lot because of the lack of the side trim. It has a recent re-paint and zero door dings right now, I have to be careful where I park to keep it that way.
It was great designing by Bill Mitchell. And in spite of the obvious benefits of the trim and its placement which were known to the designers, a conscious decision was made NOT to add the trim to the sides of the Fleetwood 60S (and 64 and up Eldorados), owing to the desire to preserve the distinctive, bare-sided look. Not until the 1970 models were the Fleetwoods and Eldorados treated to what the 63-64 62s and DeVilles had.
