Is there any official rules for the damage incurred when being dragged behind a horse or vehicle along the ground? I've looked at RUE under horsemanship and cowboy skills and didn't see anything, nor in the skill descriptions in New West.

Any ideas? Would it fall under the generic damage heading of:
thrown/dropped object
falling
collision
knockdown

1/10th Collision damage is my reasonable house rule.

Through within reason getting drug at Mach 1 will grind that armor to dust rather quickly.
