I agree with this, it does make a lot of sense for the items to be damaged. Plus, I think it’ll help make crash sites less desirable and more balanced; because as they are, they just have too much good loot - coupled with how frequently they spawn; it’s quite easy to end up with several: army helmets, gas masks, and UPS’s very quickly.
It would also be nice, if Zombie Soldiers and Zombie Grenadiers spawned here more often.
