This 7 Days to Die mod added a small change to airdrop loot, small depending on your point of view that is. Now a possibility of finding vehicle parts in airdrops.
Updated for A19
With this new version linked to the new tiered system you will get chances of the appropriate vanilla vehicle parts in air drops that correspond to player level.
If other vehicle mods have vehicle parts added to the group vehiclePartsTiered you will have chances of getting an air drop with their parts in.
Ragsy tested this with his new boats (coming soon for stable version) and he got boat parts after he reached greasemonkey level 4. This will definately not work on all of the vehicle mods out there so be warned but will work in vanilla game also.
The old vanilla parts only version is still on his git download.
The forum topic of the mod is here.
