Hi Hank,
The most irritating item I found with the box car coaches was the coil springs. Movies taken from them were very bouncy and my neighbor got motion sickness watching the tape.
Same goes for the rider gons - leaf springs would have been nice. But that is just me.
I'd like to have an outer sheath on 05635 but kept it the way it was originally not a luxury car.
But That's just me being a railfan.
