There many components of these trucks.
1) Frame numbers
2) Engine types: Victory, DA, Senior
3) Body construction materials
4) Frame type whether level top or raised over rear axle.
I own a S114xxx and a S115xxx. They have the DA 6 motor # H 79xxx and # H 88xxx.
The cabs are wood framed with steel clad components.
The frames are level over the rear axle.
I believe my trucks are essentially Graham built trucks with Dodge badges or nameplates.
There has plenty treads discussing the "E" series trucks, and good summaries of frame #'s and plant production location.
Any comment on these component would be of interest to fellow Dodge Bros collectors.
