This was a caravan owned by Cassidy Caravans and likely run by an individual by the name of "Durable Dunn." Prior to the Courier meeting Cass, the caravan was traveling through this location when it was attacked and destroyed by members of both the Crimson Caravan and Van Graffs. Unlike the other two sacked caravans in the Mojave, this one seemed to have put up fierce resistance, indicated by the bodies of two Van Graff thugs and the body of a Crimson Caravan guard.
In an area between two wooden bridges, the bodies two Van Graff thugs, one Crimson Caravan guard, and three ash piles will be found. There is a dead brahmin beneath the northern bridge. A campfire can be found at this location.
The combat armor found on the Van Graff thugs has the distinctive black skin used by the Van Graff family, although the name is still the default "combat armor."
Durable Dunn's sacked caravan appears only in Fallout: New Vegas.
