Wreckers, Tow Trucks, and other recovery vehicles.

[Spencer]

Very true, but I would assume that any raiders clever enough to start using rigs and wreckers to haul off their salvage would likely also be clever enough to have layered defenses with both anti-vehicular and anti-aircraft mounts. They might even use a fortified abandoned factory or something similar to disguise their chop shop.
I guess that it all depends on just how clever the players are: if they are running a team of duellists attempting to locate said chop shop, perhaps on contract for the 'Hood, then those defenses might just be comprehensive. If they are running the wrecker gang, how fast and how hard the 'Hood responds would depend on how effective they are at covering their tracks.
Not to mention that a Brotherhood punitive convoy rolling up on the gang in mid-salvage would be one heck of a battle.
